Description

Technical Field

[0001] This application relates to the field of mechanical equipment maintenance technology, and in particular to a reset device and method for removing stuck workpieces from equipment. Background Technology

[0002] refer to Figure 1 and Figure 2 In certain industrial applications, there exists a type of device 9 that employs a spring-energy-storage firing principle. Internally, an electrically controlled triggering mechanism releases the energy stored in a high-stiffness spring 905, driving an actuator 901 (such as an impact head, pressure head, or firing rod) forward at high speed to perform tasks such as impacting, pressing, or activating the target workpiece 10. Due to its compact structure, rapid response, and high output energy density, this type of equipment is widely used in automated assembly lines, material impact testing, and blasting auxiliary devices.

[0003] Although these devices generally use electronic triggering, which significantly reduces the probability of "trigger failure" (i.e., the actuator failing to operate normally after triggering) compared to traditional mechanical triggering, the problem of trigger failure cannot be completely avoided due to factors such as spring fatigue, solenoid valve response delay, workpiece dimensional tolerances, and ambient temperature fluctuations. When trigger failure occurs, the actuator often stops at the forward position, the internal spring remains compressed, and the faulty workpiece is stuck in the working area. At this time, the actuator must be forcibly pulled back to the rear standby position to reset the spring and open the unlocking mechanism before the stuck workpiece can be removed and the normal operation of the equipment can be restored.

[0004] However, this exclusion process faces three major difficulties in practice:

[0005] First, safety restrictions. Because the spring is still in a compressed state and there is a risk of accidental activation of the triggering mechanism, operators are strictly prohibited from standing in front of the actuator or in front of the workpiece jamming area. They must operate from the side of the equipment, which imposes strict directional constraints on the design and operation of the tool.

[0006] Second, space constraints. These devices are typically integrated into compact automated racks or mobile platforms, surrounded by pipelines, sensors, protective covers, and other components, leaving extremely limited operating space around the device itself. Operators find it difficult to obtain sufficient operating space on the sides of the equipment, let alone use large or complex external tools.

[0007] Third, mechanical limitations. To achieve high energy output and meet lightweight design requirements, these devices often use two sets of parallel high-stiffness springs as energy storage elements. When the actuator resets, it needs to overcome the enormous elastic force of these two sets of springs simultaneously. It is extremely difficult to pull the actuator directly by hand; a mechanical force amplification mechanism is often required to complete the task.

[0008] The existing methods of elimination have obvious shortcomings: if an external electric or pneumatic pulling device is used, although it can provide sufficient traction force, its structure is complex, its size is large, its weight is heavy, and it requires an additional power or air source. It is not suitable for use in a small equipment compartment, and it also contradicts the overall design goal of the equipment itself to pursue lightweight and low cost. If a simple mechanical pull rod or hook is used, it is difficult for the operator to apply sufficient pulling force when operating from the side, and it is easy to cause secondary failures or even personnel injuries due to insufficient lever arm or tool slippage.

[0009] For a long time, those skilled in the art have generally believed that such devices, which use high-stiffness springs for energy storage and are integrated in a compact space, can only rely on electric or pneumatic auxiliary devices for forced reset after firing failure. Purely human-driven mechanical structures cannot simultaneously meet the three demanding requirements of "installation in a confined space", "lateral operation" and "overcoming large spring forces". Therefore, no effective purely mechanical solution has yet emerged.

[0010] Therefore, how to achieve reliable, labor-saving, and unidirectional locking manual traction of high-rigidity spring-driven actuators without increasing the complexity of electrical systems, occupying excessive space, and ensuring that operators are always in a safe area has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0011] The purpose of this application is to provide a compact, easy-to-operate, and low-cost purely mechanical traction device for manually resetting a high-rigidity spring-driven actuator from the side of equipment in a confined space, thereby removing stuck workpieces. The technical solution is as follows:

[0012] In a first aspect, this application provides a resetting device for removing a jammed workpiece from a device, comprising: an outer frame, wherein a front-clamping and rear-hanging mounting structure is provided on the outer frame, the front-clamping and rear-hanging mounting structure being used to limit the outer frame in the horizontal, vertical and rotational directions; a motion component, wherein the motion component is slidably disposed on the outer frame, the motion component including a mounting frame and a traction pin seat fixedly connected to the mounting frame; a traction hook, wherein the bottom of the traction hook is provided with a connecting structure for detachably connecting to the tail of the actuator of the device, and the front end of the traction hook is provided with a hook groove; and a ratchet mechanism, wherein the ratchet mechanism includes a fixedly disposed... The device includes a ratchet rack on the outer frame, a ratchet rotatably mounted on the mounting frame, a stop tooth engaging with the ratchet, and a rocker arm for driving the ratchet to rotate. The front end of the traction pin seat has a pin shaft. When the outer frame is fixed to the equipment base via the front-clamp-rear-hook mounting structure, the pin shaft falls into the hook groove of the traction hook to form a traction engagement. When the rocker arm is reciprocated, the engagement between the ratchet and the ratchet rack drives the mounting frame and the traction pin seat to move backward in a unidirectional step along the outer frame. The traction pin seat, through the traction hook, drives the actuator to overcome spring resistance and move backward to a standby position, thereby opening the unlocking mechanism and removing the jammed workpiece.

[0013] Optionally, the front-clamp-rear-hook mounting structure includes a front profile located at the front of the outer frame for engaging with a mounting groove on the front guide interface of the equipment, and a mounting pin located at the rear of the outer frame for engaging with a hanging groove on the equipment base. The outer frame is detachably fixed to the equipment base via the front-clamp-rear-hook mounting structure. The front-clamp-rear-hook mounting structure also includes a manual pin located at the front side of the outer frame, with a corresponding slot provided at the front guide interface of the equipment. The front-clamp-rear-hook mounting structure is configured such that when the front profile of the outer frame is engaged with the mounting groove of the front guide interface of the equipment, the mounting pin is engaged with the hanging groove on the equipment base, and the manual pin is inserted into the slot, the outer frame is limited in the horizontal, vertical, and rotational directions.

[0014] Optionally, the actuator has an extension at its tail end, and the extension has a pin hole. The traction hook is detachably connected to the extension via the pin.

[0015] Optionally, the mounting frame is slidably disposed within the guide groove of the outer frame, and the ratchet is fixedly disposed on the outer frame along the length direction of the guide groove.

[0016] Optionally, the rocker arm is fixedly connected to the ratchet, the stop tooth is rotatably mounted on the mounting frame, and an elastic element is provided between the stop tooth and the ratchet to press the stop tooth into the groove of the ratchet.

[0017] Optionally, the traction pin seat and the mounting frame are fixedly connected by welding, and the mounting frame, the traction pin seat, and the ratchet constitute a synchronous motion unit.

[0018] Optionally, the shape of the outer frame matches the internal contour of the device, and the outer frame, the motion component, and the ratchet mechanism are all made of metal.

[0019] Optionally, the ratchet mechanism is configured as a one-way stepping traction mechanism, in which the mounting frame is locked after each backward movement when the rocker arm is reciprocated.

[0020] Secondly, this application also provides a method for removing a workpiece stuck in a device using the above-mentioned reset device, comprising the following steps:

[0021] Step 1: Install the traction hook at the tail of the actuator;

[0022] Step 2: Fix the outer frame to the equipment base using the front-clamp and rear-hook mounting structure, so that the pin at the front end of the traction pin seat falls into the hook groove of the traction hook to form a traction engagement, and then insert the manual pin into the slot.

[0023] Step 3: The operator repeatedly cranks the rocker arm on the side of the equipment. Through the one-way stepping traction of the ratchet mechanism, the mounting frame moves backward step by step, which drives the actuator to overcome the spring resistance and move backward.

[0024] Step 4: When the actuator is pulled to the rear standby position, the unlocking mechanism opens to remove the stuck workpiece;

[0025] Step 5: Remove the outer frame from the equipment base, remove the reset device, and then remove the traction hook from the tail of the actuator.

[0026] The beneficial effects of the reset device for removing stuck workpieces provided in this application embodiment include at least the following:

[0027] 1. By adopting a split-type traction hook design, the traction hook is pre-installed at the tail of the actuator. During the installation of the outer frame, the traction pin seat automatically falls into the hook groove to form a traction engagement. The entire installation process is completed on the side of the equipment, and operators do not need to enter the dangerous area in front of the equipment. At the same time, the front-clamping and rear-hanging installation structure, together with the manual pin, realizes three-way limiting of the outer frame in the horizontal, vertical and rotational directions, ensuring that the device is stable and does not fall off during dynamic operation.

[0028] 2. A unidirectional stepping traction mechanism is constructed using a ratchet and ratchet rack as its core, integrating the ratchet, stop teeth, rocker arm, and ratchet rack. When the operator reciprocates the rocker arm on the side of the equipment, each reciprocation only requires overcoming the spring deformation force corresponding to one tooth pitch. Through multiple reciprocations, the actuator is gradually pulled to the rear standby position. This design breaks down the enormous spring force that needs to be overcome in one operation into multiple small incremental operations, allowing manual labor to easily complete the task of resetting a high-stiffness spring that was originally impossible to pull directly.

[0029] 3. The installation method employs a "front-clamping, rear-hanging + manual pin" approach. The outer frame is secured in three simple steps: the front profile snaps into the mounting slot of the front guide interface of the equipment; the rear mounting pin engages with the hanging slot on the equipment base; and the manual pin is inserted into the slot. No tools are required throughout the entire process. Furthermore, the outer frame's shape matches the internal contours of the equipment, resulting in a compact and small overall structure, allowing for flexible operation within confined equipment compartments surrounded by pipelines, sensors, protective covers, and other components.

[0030] 4. It adopts a purely mechanical structure without any electrical or pneumatic components, requiring no external power or air supply, and its manufacturing cost is far lower than that of electric or pneumatic pulling devices. At the same time, the purely mechanical structure has high reliability, low failure rate, and simple maintenance, meeting the overall design goals of lightweight and low cost.

[0031] 5. This invention fully utilizes the existing structural features of the equipment, such as an extension at the tail of the actuator. This extension extends outward from the tail of the actuator to form an independent connection interface. The traction hook is detachably connected to the extension via a pin, achieving reliable installation using the existing structure of the equipment without any modification. The extension "leads" the connection point of the traction hook out of the main body of the actuator, allowing operators to clearly observe and operate the connection process from the side of the equipment. It also provides a stable installation base for the traction hook, ensuring uniform transmission of traction force.

[0032] 6. The one-way locking characteristic of the ratchet mechanism of this invention ensures that the actuator is locked after each backward movement during traction, preventing it from springing back. This function avoids the risk of the actuator springing back under spring action due to operational interruption or insufficient force, preventing secondary malfunctions and personnel injury. At the same time, the step-by-step traction allows the operator a short rest and adjustment time between each rocking motion, improving the controllability and safety of operation.

[0046] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0047] refer to Figure 1 and Figure 2 In industrial applications, there exists a type of device 9 that employs a spring-energy-storage firing principle. Internally, an electrically controlled triggering mechanism releases the energy stored in a high-stiffness spring 905, driving an actuator 901 (such as an impact head, pressure head, or firing rod) forward at high speed to perform tasks such as impacting, pressing, or activating the target workpiece 10. Although this type of device 9 generally uses electrically controlled triggering, significantly reducing the probability of "firing failure" (i.e., the actuator failing to operate normally after triggering) compared to traditional mechanical triggering, the problem of firing failure cannot be completely avoided due to factors such as spring fatigue, solenoid valve response delay, workpiece dimensional tolerances, and environmental temperature fluctuations. When firing failure occurs in device 9, the actuator 901 often stops at the forward position, the internal spring 905 remains compressed, and the faulty workpiece 10 is stuck in the working area. At this point, the actuator 901 must be forcibly pulled back to the rear standby position to reset the spring 905 and open the unlocking mechanism before the stuck workpiece 10 can be removed and the device 9 can resume normal operation. The unlocking mechanism is a component of device 9 itself, and is a known structure in the field, so it will not be described in detail here.

[0048] First aspect: According to the embodiments of this application, reference is made to Figures 3 to 7 A resetting device for removing stuck workpieces from equipment is provided, comprising: an outer frame 1, a motion component 2, a traction hook 3, and a ratchet mechanism 4.

[0049] The outer frame 1 is provided with a front-clamp and rear-hook mounting structure, which is used to limit the outer frame 1 in the horizontal, vertical and rotational directions.

[0050] The motion component 2 is slidably mounted on the outer frame 1. The motion component 2 includes a mounting frame 201 and a traction pin seat 202 fixedly connected to the mounting frame 201.

[0051] The bottom of the traction hook 3 is provided with a connection structure for detachable connection with the tail of the actuator 901 of the device 9, and the front end of the traction hook 3 is provided with a hook groove 301.

[0052] The ratchet mechanism 4 includes a ratchet rack 401 fixedly mounted on the outer frame 1, a ratchet 402 rotatably mounted on the mounting frame 201, a stop tooth 403 cooperating with the ratchet 402, and a rocker arm 404 for driving the ratchet 402 to rotate.

[0053] The front end of the traction pin seat 202 is provided with a pin 2021. When the outer frame 1 is fixed to the base of the equipment 9 by the front-clamping and rear-hanging installation structure, the pin 2021 falls into the hook groove 301 of the traction hook 3 to form a traction engagement. When the rocker arm 404 is reciprocated, the ratchet 402 and the ratchet rack 401 drive the mounting frame 201 and the traction pin seat 202 to move backward in a one-way stepping manner along the outer frame 1. The traction pin seat 202 drives the actuator 901 to move backward to the standby position through the traction hook 3, overcoming the resistance of the spring 905, so that the unlocking mechanism is opened and the stuck workpiece 10 is removed.

[0054] In this embodiment, the outer frame 1 is quickly fixed to the base of the device 9 via a front-clamping and rear-hanging installation structure. This installation structure can limit the outer frame 1 in all directions—horizontally, vertically, and in rotational direction—ensuring that the device will not loosen due to vibration or lateral force during subsequent dynamic operation, thus solving the safety hazard of "simple mechanical tools easily slipping off" in the prior art. The motion component 2 is slidably mounted on the outer frame 1, and its core consists of the mounting frame 201 and the traction pin seat 202 fixedly connected to it. The traction hook 3 is independent of the motion component 2 and is pre-installed at the tail of the actuator 901. This split design allows the operator to complete all installation steps from the side of the device 9 without entering the dangerous area in front of the device 9. After the outer frame 1 is installed in place, the pin 2021 at the front end of the traction pin seat 202 naturally falls into the hook groove 301 of the traction hook 3, forming a reliable traction engagement, which simplifies the operation process. The ratchet mechanism 4 is the core of the entire device for increasing force. The ratchet rack 401 is fixed to the outer frame 1, and the ratchet 402, stop teeth 403, and rocker arm 404 are mounted on the mounting frame 201. When the operator reciprocates to rock the rocker arm 404 on the side of the device 9, the one-way meshing characteristic of the ratchet 402 and the ratchet rack 401 locks the mounting frame 201 after each backward movement, preventing it from springing back. Through repeated rocking, the mounting frame 201 gradually moves backward, driving the actuator 901 through the traction pin seat 202 and the traction hook 3 to overcome the huge elastic force of the two parallel high-stiffness springs 905, achieving high-resistance traction that cannot be directly accomplished by human power. When the actuator 901 is pulled to the rear standby position, the unlocking mechanism of the device 9 opens, and the stuck workpiece 10 is safely discharged. Throughout the entire operation, the operator remains positioned on the side of the equipment 9. No electric or pneumatic assistance is required; the entire process can be completed manually. This solves the three major problems mentioned in the background technology: difficulty in installing in confined spaces, danger of operating from the front of the equipment, and difficulty in overcoming the large spring force by manpower.

[0055] According to the embodiments of this application, refer to Figure 3 and Figure 4 The front-card-rear-hanging mounting structure includes a front profile 101 disposed at the front of the outer frame 1 for engaging with the mounting groove 902 of the front guide interface of the device 9, and a mounting pin 102 disposed at the rear of the outer frame 1 for engaging with the hanging groove 903 on the base of the device 9. The outer frame 1 is detachably fixed to the base of the device 9 by the front-card-rear-hanging mounting structure.

[0056] The front-hook and rear-hook mounting structure also includes a manual pin 103, which is located on the front side of the outer frame 1. A corresponding slot 904 is provided at the front guide interface of the device 9. The front-hook and rear-hook mounting structure is configured such that when the front contour 101 of the outer frame 1 is inserted into the mounting slot 902 of the front guide interface of the device 9, the mounting pin 102 is inserted into the hanging slot 903 on the base of the device 9, and the manual pin 103 is inserted into the slot 904, the outer frame 1 is limited in the horizontal, vertical and rotational directions.

[0057] This embodiment specifies the front-clamp-rear-hanging installation structure. The front-clamp-rear-hanging installation structure employs a three-point fixing method: "front clamp + rear hang + side lock." Specifically, the outer frame 1 has a front contour 101 at its front, which is inserted into the mounting groove 902 of the front guide interface of the device 9 during installation, forming a vertical limiting and rotation fulcrum at the front. The outer frame 1 has a mounting pin 102 at its rear, which is inserted into the hanging groove 903 on the base of the device 9, forming a horizontal limiting at the rear. A manual pin 103 is also provided on the front side of the outer frame 1, and a corresponding slot 904 is provided at the front guide interface of the device 9. When the manual pin 103 is inserted into the slot 904, the outer frame 1 is completely locked in the rotation direction, preventing the device from tilting upwards or shifting to the side due to vibration when the rocker arm 404 is shaken.

[0058] This "three-point locking" installation method has the following significant advantages: First, the installation process requires no tools; the operator only needs to complete the process in three steps: front clamp, rear hook, and pin, making it ideal for operation in confined spaces. Second, the three locking points restrict different degrees of freedom, collectively achieving omnidirectional limiting in the horizontal, vertical, and rotational directions, ensuring reliable fixation of the reset device. Finally, the manual pin 103 design provides double safety protection; even if the front contour 101 or mounting pin 102 becomes loose due to an accident during the operation of the joystick 404, the manual pin 103 can still lock the outer frame 1 in place, preventing the reset device from accidentally coming off. This installation structure directly solves the problems of "space constraints" and "easy slippage of simple tools" in the background technology.

[0059] According to the embodiments of this application, refer to Figure 1 , Figure 2 and Figure 7 The actuator 901 has an extension body 906 at its tail end. The extension body 906 has a pin hole, and the traction hook 3 is detachably connected to the extension body 906 via a pin.

[0060] This technical solution defines the specific connection method between the traction hook 3 and the actuator 901, as well as the structural features of the actuator 901. In the actual device 9, the tail of the actuator 901 itself has an extension body 906 structure, which extends outward from the tail of the actuator 901 to form an independent and easy-to-operate connection interface. The reset device of this application embodiment utilizes the pin hole on the extension body 906, which corresponds to the pin hole at the bottom of the traction hook 3, to achieve a reliable connection through the pin. This design has the following technical contributions: First, by utilizing the original extension body 906 structure of the device 9, the reliable installation of the traction hook 3 can be achieved without any modification to the device 9; second, the extension body 906 extends the connection point of the traction hook 3 outward from the body of the actuator 901, allowing the operator to more clearly observe and operate the connection process from the side of the device 9; third, the extension body 906 provides a stable installation base for the traction hook 3, ensuring that the traction force can be evenly transmitted to the actuator 901.

[0061] Pin connection is a common mechanical connection method that allows for easy installation and disassembly in confined spaces using only simple tools. More importantly, pin connection allows the traction hook 3 to have a certain degree of rotational freedom relative to the actuator 901. This enables the pin 2021 at the front end of the traction pin seat 202 to slide more smoothly into the hook groove 301 of the traction hook 3 after the outer frame 1 is installed in place. Even minor alignment deviations can be automatically corrected, improving operational fault tolerance.

[0062] According to the embodiments of this application, refer to Figure 3 and Figure 4 The mounting frame 201 is slidably disposed in the guide groove (not shown in the figure) of the outer frame 1, and the ratchet 401 is fixedly disposed on the outer frame 1 along the length direction of the guide groove.

[0063] This technical solution defines the sliding fit between the motion component 2 and the outer frame 1. Specifically, the outer frame 1 is provided with a guide groove, and the mounting frame 201 is embedded in the guide groove and can slide freely along the length of the guide groove. The ratchet rack 401 is fixedly set on one side of the guide groove and extends along the length of the guide groove. This design ensures that the mounting frame 201 always maintains the correct trajectory during movement and will not deviate or jam. The guide groove structure plays a dual role of guiding and limiting. On the one hand, it guides the mounting frame 201 to move in a straight line, and on the other hand, it restricts its degrees of freedom in other directions, ensuring that the ratchet 402 and the ratchet rack 401 always maintain the correct meshing state. This precise sliding fit design is the basis for the stable operation of the ratchet mechanism 4. Optionally, the guide groove structure can be a sliding groove provided on the two inner sidewalls of the outer frame 1 along the length direction, and correspondingly, the two outer sidewalls of the mounting frame 201 along the length direction are provided with sliders that can be inserted into the sliding grooves.

[0064] According to the embodiments of this application, refer to Figure 3 and Figure 4 The rocker arm 404 is fixedly connected to the ratchet 402, the stop tooth 403 is rotatably mounted on the mounting frame 201, and an elastic element is provided between the stop tooth 403 and the ratchet 402 to press the stop tooth 403 into the tooth groove of the ratchet 402.

[0065] This technical solution defines the connection relationship of each component in the ratchet mechanism 4 and the clamping method of the stop tooth 403. The rocker arm 404 is fixedly connected to the ratchet 402. When the operator shakes the rocker arm 404, the ratchet 402 rotates accordingly. The stop tooth 403 is rotatably mounted on the mounting frame 201, with its front end engaging with the tooth groove of the ratchet 402. An elastic element, such as a torsion spring or compression spring, continuously applies pressure to the stop tooth 403, ensuring it remains pressed firmly within the tooth groove of the ratchet 402. This design achieves a one-way locking function for the ratchet mechanism 4: when the rocker arm 404 is pushed forward, the ratchet 402 rotates forward, and the stop tooth 403 slides on the back of the ratchet 402 teeth, allowing the ratchet 402 to move forward; when the rocker arm 404 is pulled backward, the stop tooth 403 engages with the tooth groove of the ratchet 402, preventing the ratchet 402 from rotating back, thereby locking the mounting frame 201 in its current position. The elastic element ensures reliable contact between the stop tooth 403 and the ratchet 402 groove, preventing them from disengaging even under vibration conditions and guaranteeing the reliability of one-way locking.

[0066] According to the embodiments of this application, refer to Figures 3 to 7 The traction pin seat 202 and the mounting frame 201 are fixedly connected by welding. The mounting frame 201, the traction pin seat 202 and the ratchet 402 constitute a synchronous motion unit.

[0067] This technical solution defines the connection method between the traction pin seat 202 and the mounting frame 201, and clarifies the synchronous motion relationship. The traction pin seat 202 and the mounting frame 201 are fixedly connected by welding, forming a rigid whole. When the mounting frame 201 slides on the outer frame 1, the traction pin seat 202 moves synchronously. The ratchet 402 is also mounted on the mounting frame 201, so the ratchet 402 and the traction pin seat 202 maintain a fixed relative positional relationship. This synchronous motion design ensures that the angle of each rotation of the ratchet 402 can be accurately converted into the displacement of the traction pin seat 202, thereby precisely controlling the traction distance of the actuator 901 through the traction hook 3. The welded connection has the characteristics of high connection strength, no relative motion, and good reliability, and is suitable for withstanding repeated traction loads.

[0068] According to the embodiments of this application, refer to Figure 5 and Figure 6The outer frame 1 is matched with the internal contour of the device 9. The outer frame 1, the motion component 2 and the ratchet mechanism 4 are all made of metal.

[0069] This technical solution limits the device's shape adaptability and material selection. The shape of the outer frame 1 is carefully designed to match the internal contour of the equipment 9, which means that after installation, the device can fit snugly against the internal space of the equipment 9 without interfering with surrounding pipelines, sensors, protective covers, and other components.

[0070] The outer frame 1, motion components 2, and ratchet mechanism 4 are all made of metal materials, such as steel and aluminum alloy. Metal materials have the characteristics of high strength, high rigidity, and good wear resistance, and can withstand the cyclic load generated by repeated shaking and the reaction force of the high-rigidity spring 905, ensuring that the device remains stable and reliable during long-term use.

[0071] According to the embodiments of this application, refer to Figure 3 and Figure 4 The ratchet mechanism 4 is configured as a one-way stepping traction mechanism. When the rocker arm 404 is reciprocated, the mounting frame 201 is locked after each backward movement.

[0072] In this embodiment, unidirectional step-by-step traction means that the mounting frame 201 can only move backward and cannot move forward or backward, and each time the rocker arm 404 is shaken, it only moves a tiny distance of one tooth pitch. This feature has the following technical effects: First, the unidirectional locking function ensures that the actuator 901 will not rebound under the action of the spring 905 due to operation interruption or insufficient force during traction, avoiding secondary failures and the risk of personnel injury; second, step-by-step traction decomposes the huge spring 905 force that needs to be overcome once into multiple tiny increments, and each time the rocker arm 404 is shaken, it only needs to overcome the deformation force of the spring 905 corresponding to one tooth pitch, making it easy to complete manually; third, step-by-step operation allows the operator to have a short rest and adjustment time between each shake, improving the controllability and safety of the operation.

[0073] Secondly, this application also provides a method for removing a stuck workpiece from a device using the above-mentioned reset device, comprising the following steps:

[0074] Step 1: Install the traction hook 3 at the tail of the actuator 901.

[0075] Step 2: Fix the outer frame 1 to the base of the equipment 9 using the front-clamp and rear-hook mounting structure, so that the pin 2021 at the front end of the traction pin seat 202 falls into the hook groove 301 of the traction hook 3 to form a traction engagement, and then insert the manual pin 103 into the slot 904.

[0076] Step 3: The operator shakes the rocker arm 404 back and forth on the side of the equipment 9. Through the one-way stepping traction of the ratchet mechanism 4, the mounting frame 201 moves backward step by step, which drives the actuator 901 to move backward against the resistance of the spring 905.

[0077] Step 4: When the actuator 901 is pulled to the rear standby position, the unlocking mechanism opens to remove the stuck workpiece 10.

[0078] Step 5: Remove the outer frame 1 from the base of the equipment 9, remove the reset device, and then remove the traction hook 3 from the tail of the actuator 901.

[0079] This technical solution provides a method for removing the workpiece 10 stuck in the device 9 using the aforementioned reset device. In step one, the operator first installs the traction hook 3 at the tail of the actuator 901.

[0080] In step two, the operator secures the outer frame 1 to the base of the equipment 9 using a front-clamping, rear-hanging mounting structure. Specifically, the operator first inserts the front contour 101 of the outer frame 1 into the mounting groove 902 of the front guide interface of the equipment 9, then rotates the outer frame 1 downwards so that the rear mounting pin 102 engages with the hanging groove 903 on the base of the equipment 9, and finally inserts the manual pin 103 into the slot 904. This process is completed entirely from the side of the equipment 9, without requiring entry into the dangerous area in front of the equipment 9, and without any tools, making it suitable for operation in confined spaces. Once the outer frame 1 is in place, the pin 2021 at the front end of the traction pin seat 202 naturally falls into the hook groove 301 of the traction hook 3, forming a traction engagement. This "automatic alignment" design avoids the tedious steps of manual alignment by the operator, improving operational efficiency.

[0081] In step three, the operator repeatedly cranks the rocker arm 404 from the side of device 9. Each time the rocker arm 404 is pushed forward, the ratchet 402 rotates forward, and the mounting frame 201 advances one tooth pitch; each time the rocker arm 404 is pulled backward, the stop tooth 403 engages with the groove of the ratchet 402, preventing the ratchet 402 from rotating back, and the mounting frame 201 is locked in the current position. Through repeated cranking, the mounting frame 201 gradually moves backward, driving the actuator 901 to overcome the huge elastic force of the two parallel high-stiffness springs 905 through the traction pin seat 202 and the traction hook 3, moving backward step by step. Throughout the process, the operator always operates from the side of device 9, and only a small force is required each time, completely solving the mechanical limitation problem.

[0082] In step four, when the actuator 901 is pulled to the rear standby position, the unlocking mechanism of the device 9 is triggered, the actuator 901 separates from the front body of the device 9, the stuck workpiece 10 is released and can be taken out from the safe position. At this time, the actuator 901 is held in the rear position by the locking mechanism of the device 9 itself, ensuring that the energy of the spring 905 has been safely locked.

[0083] In step five, the operator moves the manual latch 103 to disengage it from the slot 904, then rotates the outer frame 1 forward and removes it, completing the device disassembly. Finally, the traction hook 3 is removed from the tail of the actuator 901. At this point, the entire removal operation is complete, and the equipment 9 can resume normal operation.

[0084] refer to Figures 1 to 7 The working process of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the technical solution and working principle of the present invention.

[0085] This embodiment provides a reset device for removing stuck workpieces from equipment, including: an outer frame 1 with a front-clamping and rear-hanging installation structure and a manual pin 103 for three-way limiting; a motion component 2 slidably mounted on the outer frame 1; a traction hook 3 connected to the tail extension 906 of the actuator 901 via a pin; and a ratchet mechanism 4 consisting of a ratchet rack 401, a ratchet 402, a stop tooth 403, and a rocker arm 404.

[0086] The overall structure of the reset device is as follows: The outer frame 1 matches the internal contour of the device 9. It has a front contour 101 at the front, a mounting pin 102 at the rear, and a manual latch 103 on the front side. The device 9 has a mounting groove 902 and a slot 904 at the front guide interface, and a hanging groove 903 on the base. The motion component 2 includes a mounting frame 201 and a traction pin seat 202 fixedly connected thereto. The mounting frame 201 is embedded in the guide groove of the outer frame 1 and can slide along the guide groove. The traction hook 3 is an independent component with a pin hole at its bottom, detachably connected to the extension 906 at the tail of the actuator 901 via a pin. Its front end has a hook groove 301. A ratchet rack 401 is fixedly mounted on one side of the guide groove of the outer frame 1. A ratchet 402 and a stop tooth 403 are rotatably mounted on the mounting frame 201. A rocker arm 404 is fixedly connected to the ratchet 402, and an elastic element is provided between the stop tooth 403 and the ratchet 402.

[0087] When device 9 fails to fire and actuator 901 is stuck in the forward position, the operator shall follow these steps:

[0088] First, the operator attaches the traction hook 3 to the extension 906 at the tail of the actuator 901 using a pin on the side of the device 9. Since the extension 906 extends outward from the tail of the actuator 901, the operator can clearly see the connection point, allowing the operation to be completed smoothly even in low light or confined spaces.

[0089] Next, the operator installs the outer frame 1 onto the base of the equipment 9. The specific installation process is as follows: First, the front contour 101 of the outer frame 1 is inserted into the mounting groove 902 of the front guide interface of the equipment 9, forming a vertical limit and rotation fulcrum at the front; then, the outer frame 1 is rotated downwards by approximately 30 degrees, causing the rear mounting pin 102 to engage with the hanging groove 903 on the base of the equipment 9, forming a horizontal limit at the rear; finally, the manual pin 103 on the front side of the outer frame 1 is pushed into the slot 904 at the front guide interface of the equipment 9, locking the rotational freedom of the outer frame 1. At this point, the outer frame 1 is reliably limited in the horizontal, vertical, and rotational directions, and even if significant vibrations or lateral forces occur during subsequent operations, the outer frame 1 will not loosen. During the installation of the outer frame 1, the pin 2021 at the front end of the traction pin seat 202 automatically falls into the hook groove 301 of the traction hook 3, forming a traction engagement, requiring no additional alignment by the operator.

[0090] Next, the operator holds the rocker arm 404 on the side of the equipment 9 and begins to rock it back and forth. When the rocker arm 404 is pushed forward, the ratchet 402 rolls forward on the ratchet rack 401, causing the mounting frame 201 and the traction pin seat 202 to move forward one tooth pitch. When the rocker arm 404 is pulled backward, the stop tooth 403, under the action of the elastic element, engages with the tooth groove of the ratchet 402, preventing the ratchet 402 from rotating. At the same time, the rocker arm 404 causes the mounting frame 201 and the traction pin seat 202 to move backward one tooth pitch. Since the ratchet rack 401 is fixed on the outer frame 1, the one-way meshing characteristic of the ratchet 402 and the ratchet rack 401 ensures that the mounting frame 201 is locked after each backward movement and cannot spring back forward. By repeatedly rocking the rocker arm 404, the mounting frame 201 gradually moves backward, and the traction pin seat 202, through the traction hook 3, drives the actuator 901 to overcome the huge elastic force of the two parallel high-stiffness springs 905, moving backward step by step. Each rocking motion only requires overcoming the deformation force of the spring 905 corresponding to one tooth pitch, which is easily borne by human power.

[0091] Finally, when actuator 901 is pulled to the rear standby position, the unlocking mechanism of device 9 is triggered, actuator 901 separates from the front body of device 9, and the stuck workpiece 10 is released and removed from the safe position. At this time, actuator 901 is held in the rear position by the locking mechanism of device 9 itself, and the energy of spring 905 has been safely locked. The operator then moves the manual latch 103 to disengage it from the slot 904, rotates the outer frame 1 forward and removes it, removes the reset device, and then removes the traction hook 3 from the tail of actuator 901 to complete the entire removal operation.

[0092] Throughout the entire operation, the operator always stands to the side of the equipment 9 and never enters the danger zone in front of the equipment 9; the installation and disassembly of the device do not require any tools and can be completed quickly in a confined space; the operator only needs to rock the rocker arm 404 back and forth to overcome the resistance of the high-rigidity spring 905, which cannot be pulled directly by manpower; the one-way locking function of the ratchet mechanism 4 ensures that the actuator 901 will not spring back during the traction process, making the operation safe and reliable.

[0093] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0094] Furthermore, various different implementations of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed in this application.
