Description

Technical Field

[0001] This application relates to the field of building material transportation technology, and in particular to an auxiliary ladder handling device. Background Technology

[0002] Building material handling is a crucial part of home renovation. If the building has an elevator, materials can be moved using that elevator; otherwise, manual handling is necessary. Traditional manual handling relies on workers carrying materials to designated floors, which is not only inefficient but also extremely costly in terms of labor.

[0003] Currently, there are also tracked transport vehicles on the market used to assist in the handling of goods. These vehicles can move up stairs by installing electric tracks on the bottom of the cargo box, which not only reduces the labor intensity of handling but also improves handling efficiency. However, when tracked transport vehicles move up stairs, they are prone to slipping due to factors such as track wear, dirt adhering to the tracks, slippery stairs, and irregular step shapes. In some cases, the entire vehicle may even slide backward down the stairs, posing a significant safety hazard. Utility Model Content

[0004] To address or partially address the problems existing in the related technologies, this application provides an auxiliary ladder-climbing transport device. This device, by setting a locking mechanism and using it in conjunction with a control component, can automatically deploy the locking component when the operating lever is out of the worker's control, preventing the device from sliding back down the stairs and ensuring the safety of the transport process.

[0005] This application provides an auxiliary ladder-climbing and transporting device, comprising:

[0006] A frame and electric tracks, with electric tracks symmetrically installed on both sides of the frame;

[0007] The locking mechanism prevents the device from sliding off the stairs. The locking mechanism includes a locking claw, a support rod, and an electric telescopic rod. The front end of the frame is symmetrically provided with mounting blocks. The locking claw is hinged to the mounting block, and the support rod is provided vertically at the mounting block. One end of the electric telescopic rod is hinged to the support rod, and the other end is hinged to the locking claw. By controlling the extension or retraction of the electric telescopic rod, the locking claw can rotate around its hinge point.

[0008] The control component allows for the extension or retraction of the electric telescopic rod.

[0009] Optionally, in some embodiments, the locking claw is fitted with an anti-slip sleeve.

[0010] Optionally, in some embodiments, an operating lever is hinged to the front end of the frame, and a handle is provided at the end of the operating lever.

[0011] Optionally, in some embodiments, a control component corresponding to the electric telescopic rod is installed at the handle, including a controller and a spring grip. The controller is fixedly installed at the handle, and the controller is respectively provided with a retraction button and an extension button for controlling the electric telescopic rod. The operating rod is also equipped with a spring grip corresponding to the extension button. When the spring grip is not disturbed by external force, it can press the extension button under the action of elasticity.

[0012] Optionally, in some embodiments, a cargo bin is fixedly mounted on the frame.

[0013] Optionally, in some embodiments, the cargo hopper has a square structure, with symmetrical slots in the middle of the cargo hopper, and baffles are slidably connected in the slots.

[0014] The technical solution provided in this application may include the following beneficial effects:

[0015] This application utilizes an electric telescopic rod to drive the locking claw to rotate around its hinge. When transporting building materials, the worker grips the elastic handle, moving it away from the extension button. At this time, the electric telescopic rod shortens, and the locking claw lifts away from the stairs. When the device slips or retracts, the worker releases the elastic handle, which rebounds and triggers the extension button. At this time, the electric telescopic rod extends, and the locking claw approaches and grips the steps, preventing the device from sliding down the stairs and improving the safety of the handling process.

While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0028] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] See Figure 1-7 An auxiliary ladder transport device includes a frame 1 and electric tracks 2. The frame 1 is welded from square steel pipes. Electric tracks 2 are symmetrically installed on the left and right sides of the frame 1. The electric tracks 2 are existing technology, and their structure and control methods will not be described in detail here. A battery is also installed on the frame 1 for convenient power supply.

[0032] This device also includes:

[0033] The locking mechanism 5 prevents the device from slipping on stairs, ensuring safety during transport. The locking mechanism 5 includes a locking claw 52, ​​a support rod 54, and an electric telescopic rod 56. A mounting block 51 is symmetrically welded to the front end of the frame 1. The locking claw 52 is hinged to the mounting block 51, and a connecting rod 53 is mounted on the locking claw 52. The support rod 54 is also vertically welded to the mounting block 51, and a support 55 is fixed to the top of the support rod 54. One end of the electric telescopic rod 56 is hinged to the support 55, and the other end is hinged to the connecting rod 53. By controlling the extension or retraction of the electric telescopic rod 56, the locking claw 52 can rotate around its hinge point. During ladder-climbing transport, the electric telescopic rod 56 is in the retracted state, at which time the locking claw 52 is raised away from the step, facilitating the device's movement. When the device slips or slides on the stairs, by controlling the extension of the electric telescopic rod 56, the locking claw 52 approaches and grips the step, thereby securing the device and ensuring safety during transport. Furthermore, an anti-slip sleeve 57 is fitted onto the locking claw 52. The anti-slip sleeve 57 is usually made of rubber, which can improve the gripping ability of the locking claw 52. It should be noted that, due to the large gaps between the steps of the staircase, when the locking claw 52 is extended, there may be a phenomenon of missing the step (the locking claw 52 does not contact the step), and it cannot immediately prevent slippage. However, as long as the locking claw 52 is extended, the device can slide back one step to allow the locking claw 52 to grab the step, without affecting the effectiveness of the locking claw 52. Similarly, there may be a situation where the locking claw 52 does not immediately grab the step when it is extended. In this case, as the device slides back, the locking claw 52 can then grab the next step.

[0034] To facilitate workers in guiding the movement of this device, a connecting seat 41 is welded at the middle position of the front end of the frame 1. An operating rod 4 is hinged to the connecting seat 41, and a handle 42 is provided at the end of the operating rod 4. When in use, workers hold the handle 42 to facilitate guiding the movement of this device.

[0035] Furthermore, a control component 6 is installed at the handle 42. The extension or retraction of the electric telescopic rod 56 can be controlled by the control component 6, and it can detect whether the worker's palm has come off the handle 42. If it has not come off, the device will move normally. If it has come off, it means that an accident has occurred during the movement. At this time, the locking mechanism 5 will be automatically deployed to prevent the device from sliding off the stairs and ensure the safety of the transportation process.

[0036] The control component 6 includes a controller 61 and a spring-loaded grip 64. A crossbar 43 is fixedly installed at the handle 42. The controller 61 is fixedly mounted on the crossbar 43 and has two buttons: a retraction button 62 and an extension button 63. When the retraction button 62 is pressed, the electric telescopic rod 56 shortens, causing the locking claw 52 to lift away from the ground. When the extension button 63 is pressed, the electric telescopic rod 56 extends, causing the locking claw 52 to approach and grip the step, thereby securing the device. It should be noted that the circuit structure and control method of the controller 61 are existing technologies, and those skilled in the art can adjust them according to actual needs, which will not be elaborated here. The elastic grip 64 includes a mounting bracket 641, a grip 642, and a torsion spring (not shown in the figure). The mounting bracket 641 is fixedly mounted on the operating lever 4. The grip 642 is hinged to the mounting bracket 641, and a torsion spring is provided between the mounting bracket 641 and the grip 642. Under the action of the elastic force, the grip 642 is biased towards the controller 61, and the end of the grip 642 corresponds to the position of the extension button 63. When the grip 642 is not disturbed by external force, the extension button 63 can be pressed under the action of the elastic force, causing the electric telescopic rod 56 to extend and the locking claw 52 to unfold. Under normal circumstances, the electric telescopic rod 56 is in the retracted state. When carrying items up stairs, see [reference needed]. Figure 5 The worker grips handle 642 firmly, ensuring it contacts handle 42 and moves away from extension button 63. If slippage or other abnormalities occur during stair climbing, the worker releases handle 642. (See below) Figure 6 The handle 642 springs back under the action of elasticity and presses the extension button 63, thereby controlling the extension of the electric telescopic rod 56, unfolding the locking claw 52, ​​and fixing the device in place, making it convenient for workers to handle abnormal situations.

[0037] In some embodiments, to facilitate loading building materials, a cargo bin 3 is fixedly installed on the frame 1. The cargo bin 3 has a square structure, and symmetrical slots 31 are opened in the middle of the cargo bin 3. A baffle 32 is slidably connected in the slots 31. The purpose of setting the baffle 32 is that, due to the incline of the stairwell, goods are prone to slide back to the rear of the cargo bin 3 under the action of gravity, resulting in uneven weight distribution in the cargo bin 3, with a heavier weight at the rear and a lighter weight at the front, which is not conducive to climbing stairs and carrying. By setting the baffle 32, the uniformity of weight distribution of goods can be improved. Furthermore, when transporting pipe fittings or other building materials, the baffle 32 can be removed to obtain a larger loading space.

[0038] Specific work process:

[0039] Normally, to prevent the elastic handle 64 from pressing the extension button 63, the handle 642 can be tied to the handle 42 with a cable tie. When climbing stairs, the goods are loaded into the cargo bin 3, and the handle 642 is untied. The worker then grips the handle 642 to guide the device up the stairs. If any abnormal situation occurs during the climb, the worker releases the handle 642, which springs back under the action of the elasticity and presses the extension button 63, thereby controlling the extension of the electric telescopic rod 56 and unfolding the locking claw 52 to fix the device in place, making it convenient for the worker to handle abnormal situations. After the situation is resolved, the worker grips the handle 642 again and presses the retraction button 62 to lift the locking claw 52 away from the ground and resume normal movement.
