Description

Technical Field

[0001] This utility model relates to the field of heavy equipment installation technology, and in particular to an equipment installation and adjustment device suitable for confined spaces. Background Technology

[0002] In industrial settings such as underground coal mine tunnels, coal preparation plants, and chemical plant workshops, the installation and replacement of heavy equipment such as motors, speed reducers, and water pumps often present severe challenges. These working environments are typically confined to narrow spaces and surrounded by various pipes, supports, cable trays, and other obstacles, making it impossible for traditional large lifting equipment such as bridge cranes to enter and operate.

[0003] Currently, in such confined spaces, manual lifting tools such as chain hoists and winches are mainly relied upon. However, these tools have significant drawbacks, such as: laborious operation and low positioning accuracy: chain hoists require operators to continuously and forcefully pull the chain, resulting in high physical exertion, and the movement of the equipment is entirely manual. When aligning the equipment with the flanges and bolt holes of the mounting base, it is difficult to achieve millimeter-level precision adjustments, often requiring repeated attempts, leading to low efficiency; significant safety hazards: in confined spaces, large-scale manual operation can easily cause the equipment to collide with surrounding obstacles; more importantly, these tools usually lack reliable self-locking braking functions, and during the suspension or fine-tuning of heavy objects, accidental slippage or falls are highly likely if there is an operational error or lapse in manpower; low work efficiency: due to the laborious operation and difficult positioning, multiple workers are usually required to work together, consuming a significant amount of time.

[0004] In summary, there is an urgent need for a compact equipment installation solution suitable for limited spaces that integrates three key functions: "labor-saving drive," "precise fine-tuning," and "safety self-locking." Utility Model Content

[0005] In view of this, this application provides an equipment installation and adjustment device suitable for confined spaces. The main objective is to solve the technical problems of laborious operation, low positioning accuracy, high safety risks, and low work efficiency in the prior art when installing heavy equipment in confined spaces.

[0006] According to the present invention, an equipment installation and adjustment device suitable for limited space is provided, including an equipment support base that can move along the length of a load-bearing guide rail. The equipment support base is used to support the equipment to be installed. The device also includes: a power conversion mechanism for amplifying the input operating force and driving the equipment support base to move; and a reverse stop mechanism connected to the power conversion mechanism for locking the equipment support base when the operating force is stopped.

[0007] Furthermore, the power conversion mechanism includes a sprocket driven by a guide chain, and a multi-stage gear transmission mechanism connected to the guide sprocket, the multi-stage gear transmission mechanism being used to amplify torque.

[0008] Furthermore, the multi-stage gear transmission mechanism includes a primary gear transmission mechanism and a secondary gear transmission mechanism, which are connected in series for a second torque amplification. Specifically, the primary gear transmission mechanism includes a driving gear, a first driven gear, and a second driven gear; the secondary gear transmission mechanism includes a center gear, a second gear, and a third gear.

[0009] Furthermore, the backstop mechanism includes a ratchet and a pawl mechanism that cooperates with the ratchet, the pawl mechanism being used to restrict the unidirectional rotation of the ratchet.

[0010] Furthermore, the anti-reverse mechanism also includes a brake disc and a pressure disc coaxially arranged with the ratchet; and an adjusting sleeve and a tightening nut for adjusting the tightening force of the pressure disc on the ratchet and the brake disc.

[0011] Furthermore, the device also includes: a guide screw, which is connected to the backstop mechanism; the equipment support is threadedly engaged with the guide screw, and the rotation of the guide screw drives the equipment support to generate linear displacement along the load-bearing guide rail.

[0012] Furthermore, the equipment support base is provided with radial adjusting nuts and height adjusting nuts for adjusting the installation position of the equipment.

[0013] Furthermore, the device supports the load-bearing guide rail via support feet.

[0014] Furthermore, the guide sprocket is coaxially connected to the input gear of the primary gear transmission mechanism via a chain; the output gear of the primary gear transmission mechanism meshes with the input gear of the secondary gear transmission mechanism to achieve a second torque amplification of the operating force and transmit it to the guide screw; one end of the guide screw is fixedly connected to the output gear shaft of the secondary gear transmission mechanism via a coupling, and the other end of the guide screw passes through a threaded hole on the equipment support and engages with it to convert the rotational motion into the linear displacement of the equipment support.

[0015] Furthermore, the ratchet is coaxially and fixedly connected to the output gear shaft of the secondary gear transmission mechanism; the pawl mechanism is hinged to the device frame via a pin, and the pawl teeth of the pawl mechanism are unidirectionally locked to the tooth groove of the ratchet; the brake disc and the clamping disc are sequentially sleeved on the ratchet in the axial direction, and the brake disc contacts the end face of the ratchet; the clamping disc is connected to the device frame via the adjusting sleeve and the tensioning nut, and the clamping force of the clamping disc on the brake disc and the ratchet is adjusted by rotating the tensioning nut to achieve braking and releasing of the ratchet.

[0016] Beneficial effects This utility model provides an equipment installation and adjustment device suitable for confined spaces. This application uses a multi-stage gear transmission system as the power conversion mechanism. The operator only needs to apply a small force to pull the guide chain, and this force is amplified step-by-step through the gear set to generate a powerful torque sufficient to drive heavy equipment. This labor-saving design allows for easy operation by a single person. Simultaneously, the small manual input corresponds to a small linear displacement of the equipment, greatly improving the alignment accuracy and controllability during equipment installation. Furthermore, this application connects a ratchet and pawl-type backstop mechanism in series with the transmission system. This means that power is only allowed to be transmitted in the forward direction of the equipment. Once the operator stops pulling the guide chain, the pawl immediately engages the ratchet, instantly locking the entire transmission system and firmly fixing the equipment support in its current position. This purely mechanical, passive self-locking method fundamentally eliminates the risk of accidental equipment slippage, greatly improving operational safety.

[0017] The entire device of this application adopts pure mechanical transmission and does not require hydraulic pumps, oil pipes and other components. The overall structure is compact and occupies little space. It can be easily deployed in narrow environments with various pipes and supports, solving the problem that traditional large lifting equipment cannot enter.

[0018] Finally, the equipment support base in this application integrates radial and height adjustment nuts, which can be precisely fine-tuned in multiple dimensions after the position of the main body of the equipment is determined, ensuring the alignment of the equipment with the mounting base, and further improving installation accuracy and efficiency.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example: Figure 1-8As shown, this utility model provides an equipment installation and adjustment device suitable for confined spaces. Its main structure consists of a load-bearing guide rail 304 and an equipment support base 302 that can move along its length. The load-bearing guide rail 304 is securely fixed to the ground by multiple adjustable height and angle support feet 307. The heavy equipment to be installed is placed on the equipment support base 302.

[0028] In one feasible implementation, the core of this device lies in its unique drive and braking system, which consists of a power conversion mechanism 1 and a reverse stop mechanism 2 connected in series. Specifically, the power conversion mechanism 1 is used to amplify the input operating force and drive the equipment support 302 to move; the reverse stop mechanism 2 is connected to the power conversion mechanism 1 and is used to lock the equipment support 302 when the operating force is stopped.

[0029] In one feasible embodiment, the power conversion mechanism 1 includes a sprocket 103 driven by a guide chain 104, and a multi-stage gear transmission mechanism connected to the guide sprocket 103. The multi-stage gear transmission mechanism is used to amplify torque. Specifically, the guide sprocket 103 is fixedly connected to the gear shaft 109A. When the guide chain 104 is pulled, the guide sprocket 103 is driven to rotate against resistance, transmitting torque to the gear shaft 109A. The multi-stage gear transmission mechanism includes a primary gear transmission mechanism and a secondary gear transmission mechanism. The guide sprocket 103 is coaxially connected to the input gear of the primary gear transmission mechanism via a chain. The output gear of the primary gear transmission mechanism meshes with the input gear of the secondary gear transmission mechanism for a second torque amplification. The second amplified torque is transmitted to the guide screw 301. Specifically, the primary gear transmission mechanism includes a driving gear 105A, a first driven gear 105B, and a second driven gear 105C; the secondary gear transmission mechanism includes a center gear 107A, a second gear 107B, and a third gear 107C; and the primary gear transmission shaft system includes a first gear shaft 109A, a second gear shaft 109B, and a third gear shaft 109C.

[0030] The working principle of the power conversion mechanism 1 is as follows: The operator pulls the guide chain 104 to rotate the guide sprocket 103. The guide sprocket 103 drives the drive gear 105A in the first-stage gear transmission mechanism to rotate via the first gear shaft 109A. The drive gear 105A meshes with the first driven gear 105B and the second driven gear 105C. Preferably, the gear ratio of the drive gear 105A to the first driven gear 105B and the second driven gear 105C is 3:1. In this application, due to the design of the gear ratio of the drive gear 105A to the first driven gear 105B and the second driven gear 105C, the torque is amplified for the first time here. Then, the first driven gear 105B and the second driven gear 105C drive the gears 107B and 107C in the second-stage gear transmission mechanism to rotate via the second gear shaft 109B and the third gear shaft 109C in the first-stage gear transmission system, respectively. Preferably, the support platform 111 is used to position and support the second gear shaft 109B and the third gear shaft 109C. The second gear 107B and the third gear 107C mesh with the central gear 107A respectively, achieving a second amplification of torque. After these two stages of amplification, the initial manual input is significantly enhanced, sufficient to drive heavy objects.

[0031] In this embodiment, the amplified torque is transmitted to the power transmission gear 108 through the secondary gear transmission shaft 110. The power transmission gear 108 meshes with the internal gear 201 to transmit power to the backstop mechanism 2.

[0032] In one feasible implementation, the backstop mechanism 2 is crucial for ensuring safety. Specifically, the backstop mechanism 2 includes a ratchet 204 and a pawl mechanism 209 that cooperates with the ratchet 204, the pawl mechanism 209 being used to limit the unidirectional rotation of the ratchet 204. The backstop mechanism 2 also includes a brake disc 206 and a pressure disc 207 coaxially arranged with the ratchet 204; and an adjusting sleeve 202 and a tensioning nut 203 for adjusting the tensioning force of the pressure disc 207 on the ratchet 204 and the brake disc 206.

[0033] In this embodiment, the internal gear 201 is fixedly connected to the force transmission shaft 208. A ratchet 204, a brake disc 206, and a pressure disc 207 are sequentially mounted on the force transmission shaft 208.

[0034] The ratchet 204 is coaxially and fixedly connected to the output gear shaft of the secondary gear transmission mechanism; the pawl mechanism 209 is hinged to the device frame via a pin, and the pawl teeth of the pawl mechanism 209 are unidirectionally locked to the tooth grooves of the ratchet 204; the brake disc 206 and the clamping disc 207 are sequentially sleeved on the ratchet 204 in the axial direction, and the brake disc 206 contacts the end face of the ratchet 204; the clamping disc 207 is connected to the device frame via the adjusting sleeve 202 and the tightening nut 203. Specifically, when the force transmission shaft 208 rotates in the forward direction, i.e., when the equipment moves forward, the ratchet 204 is driven to rotate, and its ratchet teeth slide over the pawl tips of the pawl mechanism 209. Once the pull of the guide chain 104 stops, the device tends to move backward under the action of gravity, which will cause the force transmission shaft 208 to attempt to reverse. At this time, the pawl mechanism 209 will immediately lock one of the ratchet teeth of the ratchet 204, thereby preventing the entire transmission system from rotating in the opposite direction and achieving reliable self-locking.

[0035] In this embodiment, the device further includes a guide screw 301, which is connected to the backstop mechanism 2. Specifically, the force transmission shaft 208 of the backstop mechanism is fixedly connected to the guide screw 301 in the support adjustment mechanism 3. The rotation of the guide screw 301, through its engagement with the threaded hole on the equipment support 302, converts the rotational motion of the guide screw 301 into precise linear motion of the equipment support 302 along the load-bearing guide rail 304. The rollers 303 at the bottom of the equipment support 302 roll on the load-bearing guide rail 304 to ensure smooth movement.

[0036] In one feasible implementation, when final precise alignment is required, the equipment support 302 is provided with a radial adjusting nut 305 and a height adjusting nut 306 for adjusting the equipment's installation position. The operator can rotate the radial adjusting nut 305 and the height adjusting nut 306 on the equipment support 302 to achieve fine adjustments to the equipment in the horizontal and vertical directions, respectively.

[0037] In one feasible embodiment, the device further includes a protective shell 101 sleeved around the outer periphery of the guide sprocket 103 and a gear transmission mechanism protective shell 102 sleeved around the outer periphery of the transmission mechanism, for normal operation in harsh environments such as high dust concentration and humidity, thereby extending the service life of the device.

[0038] In summary, this device, through its transmission chain of "manual input → multi-stage gear amplification → ratchet and pawl backstop → lead screw drive output," perfectly solves the problem of labor-saving, safe, and precise installation of heavy equipment within a limited space.
