DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0028] The embodiment of the present application provides a hoisting auxiliary device, which solves the problem that the existing hoisting auxiliary device is mostly used for specific electromechanical equipment, and realizes that the hoisting auxiliary device can effectively fix various types of electromechanical equipment and can adapt to various hoisting requirements.

[0029] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings of the specification and specific embodiments.

[0030] As shown in Figure 1 , the embodiment of the present application provides a hoisting auxiliary device, which includes:

[0031] The beam 1, the connecting piece 2, the bidirectional screw rod 4, the sliding assembly 3, the positioning assembly 5 and the extrusion assembly 6;

[0032] The connecting piece 2 is fixedly installed at both ends of the beam 1, and the connecting piece 2 is used for being connected with a traction piece of a hoisting device;

[0033] The bidirectional screw rod 4 is installed in the inside of the beam 1, the two ends of the bidirectional screw rod 4 are provided with thread segments with opposite rotation directions, the two sliding assemblies 3 are respectively installed on the thread segments at the two ends of the bidirectional screw rod 4, and the bidirectional screw rod 4 is used for driving the two sliding assemblies 3 to move in opposite directions along the axis of the bidirectional screw rod 4;

[0034] The positioning assembly 5 is connected with the sliding assembly 3 at one end of the bidirectional screw rod 4, and the positioning assembly 5 is used for fixing one end of the electromechanical equipment;

[0035] The extrusion assembly 6 is connected with the sliding assembly 3 at the other end of the bidirectional screw rod 4, and the extrusion assembly 6 is used for extruding the other end of the electromechanical equipment.

[0036] Specifically, the connecting piece 2 can be a hanging ring as shown in Figure 1 , and can also be a hook or other connecting piece used for connecting the end of the traction piece of the hoisting device. The traction piece of the hoisting device can be a chain of a manual hoist. As shown in Figure 2 , the bidirectional screw rod 4 is rotatably installed in the beam 1, the two ends of the bidirectional screw rod 4 are rotatably installed in the beam 1 through bearings, the two ends of the bidirectional screw rod 4 have thread segments, the rotation directions of the thread segments at the two ends are opposite, and the lengths of the two thread segments can be equal. When the bidirectional screw rod 4 rotates, the two sliding assemblies 3 installed thereon move towards or away from each other.

[0037] In the embodiment, as shown in Figure 1As shown, two sliding components 3 are provided at both ends of the crossbeam 1. When the bidirectional lead screw 4 inside the crossbeam 1 is rotated, the two sliding components 3 move towards each other, causing the positioning component 5 and the pressing component 6 to move towards each other, placing the electromechanical equipment between the positioning component 5 and the pressing component 6. The positioning component 5 fixes one end of the electromechanical equipment, and the pressing component 6 presses and supports the other end of the electromechanical equipment. As the positioning component 5 and the pressing component 6 gradually approach each other, the electromechanical equipment is clamped by the positioning component 5 and the pressing component 6. For example, if the electromechanical equipment is a motor, one end of the motor is fixed by the positioning component 5, and the other end of the motor is supported by the pressing component. The gradually approaching positioning component 5 and the pressing component 6 clamp the motor. Since the distance between the positioning component 5 and the pressing component 6 is adjustable, different types of electromechanical equipment can be clamped and fixed, adapting to various different hoisting needs and expanding the application range of the hoisting device.

[0038] In optional embodiments of this application, such as Figure 2 As shown, a sliding groove 11 is provided inside the crossbeam 1, and the bidirectional lead screw 4 is installed in the sliding groove 11. The two ends of the bidirectional lead screw 4 are respectively rotatably installed at both ends of the crossbeam 1. Specifically, as... Figure 2 As shown, a groove 11 is provided on the lower surface of the crossbeam 1, and the cross-sectional shape of the crossbeam 1 is generally [missing information]. Bearings are installed at both ends of the crossbeam 1, and the two ends of the double-acting lead screw 4 are mounted on the bearings at both ends of the crossbeam 1 to facilitate the rotation of the double-acting lead screw 4. The double-acting lead screw 4 is installed in the slide groove 11 to save installation space, and the slide groove 11 also protects the double-acting lead screw 4. In addition, a knob 7 is installed at one end of the double-acting lead screw 4, and rotating the knob 7 makes it easier to drive the double-acting lead screw 4 to rotate.

[0039] In optional embodiments of this application, such as Figure 2 As shown, the sliding assembly 3 includes a sliding sleeve 31 and a slider 32. The sliding sleeve 31 is slidably mounted on the crossbeam 1, and the slider 32 is slidably mounted in the slide groove 11. The sliding sleeve 31 is connected to the slider 32. The sliders 32 in the two sliding assemblies 3 are respectively assembled on the threaded sections at both ends of the bidirectional lead screw 4.

[0040] Specifically, taking the center plane along the length of the beam 1 as the plane of symmetry, two sliders 32 are symmetrically installed in the slide groove 11. The slide groove 11 protects the sliders 32 on one hand and restricts their rotation on the other. The slide groove 11 guides the sliders 32 to make linear movements within it. A bidirectional lead screw 4 passes through the two sliders 32 and is threadedly connected to the two sliders 32. Figure 2 As shown, the bottom of the slider 32 is fixedly connected to the sliding sleeve 31, which is fitted onto the crossbeam 1. When the bidirectional lead screw 4 is rotated, the two sliders 32 move closer to each other or further apart. The movement of the two sliders 32 drives the movement of the two sliding sleeves 31, thereby driving the positioning component 5 and the pressing component 6 to move simultaneously.

[0041] In optional embodiments of the present application, as shown in Figure 1 and Figure 2 The sliding assembly 3 further comprises a first locking bolt 33, which penetrates the side wall of the sliding sleeve 31 and is threadedly connected with the side wall of the sliding sleeve 31.

[0042] Specifically, when the sliding sleeve 31 is moved to the end, the first locking bolt 33 can be tightened to press the surface of the crossbeam 1. At this time, the end surface of the first locking bolt 33 has a large friction with the surface of the crossbeam 1, so that the first locking bolt 33 is difficult to move along the length direction of the crossbeam 1. Since the first locking bolt 33 is installed on the sliding sleeve 31, the fixing of the sliding sleeve 31 is achieved.

[0043] In optional embodiments of the present application, as shown in Figure 1 and Figure 3 The positioning assembly 5 comprises a first connecting rod 51, an end plate 52, and a pressing screw 54. One end of the first connecting rod 51 is connected with the sliding sleeve 31 in one of the sliding assemblies 3, and the other end of the first connecting rod 51 is connected with the end plate 52. The end plate 52 is provided with an axle hole 53 for accommodating the protruding shaft of the electromechanical equipment. The pressing screw 54 is threadedly installed on the side wall of the end plate 52, and one end of the pressing screw 54 penetrates the side wall of the end plate 52 and extends into the axle hole 53.

[0044] Specifically, the protruding shaft or columnar structure of the electromechanical equipment can be placed in the axle hole 53. For example, the shaft head of the motor is first placed in the axle hole 53, and then the pressing screw 54 is tightened to fix the shaft head, thereby achieving the purpose of fixing one end of the electromechanical equipment and avoiding movement of the electromechanical equipment during hoisting, thereby ensuring hoisting safety.

[0045] In optional embodiments of the present application, as shown in Figure 1 and Figure 3 The pressing assembly 6 comprises a second connecting rod 61, a pressing plate 62, a supporting plate 63, and a second locking bolt 64. One end of the second connecting rod 61 is connected with the sliding sleeve 31 in the other of the sliding assemblies 3. The pressing plate 62 is provided with a sliding groove near one end of the second connecting rod 61. The other end of the second connecting rod 61 is slidingly installed in the sliding groove of the pressing plate 62. The supporting plate 63 is fixedly connected to the end of the pressing plate 62 away from the second connecting rod 61, and is installed on the side of the pressing plate 62 close to the positioning assembly 5. The second locking bolt 64 is threadedly installed on the pressing plate 62, and one end of the second locking bolt 64 penetrates the side wall of the pressing plate 62 and extends into the sliding groove of the pressing plate 62.

[0046] Specifically, the electromechanical equipment is placed on the supporting plate 63, the length and width of the supporting plate 63 can be designed according to the size of the chassis of the electromechanical equipment to be hoisted. Then the length of the second connecting rod 61 extending into the pressing plate 62 is adjusted, so that the electromechanical equipment is kept in a stable state between the positioning assembly 5 and the pressing assembly 6, the axis of the extension shaft of the electromechanical equipment is kept parallel to the axis of the shaft hole 53, and then the position of the second connecting rod 61 is fixed by locking the second locking bolt 64, so that the positional relationship between the second connecting rod 61 and the pressing plate 62 is fixed. When hoisted, the pressing plate 62 in the pressing assembly 6 and the end plate 52 press the electromechanical equipment, preventing the electromechanical equipment from moving, and the supporting plate 63 supports the electromechanical equipment.

[0047] In optional embodiments of the present application, as shown in Figure 1 and Figure 3 , the hoisting auxiliary device further comprises a guiding assembly 8, which is located between the two connecting members 2 and is installed on the cross beam 1, and is used to limit the swinging of the traction member connected with the connecting member 2.

[0048] Specifically, as shown in Figure 3 , the guiding assembly 8 comprises a supporting rod 81 and a cross plate 82, the supporting rod 81 is installed on the cross beam 1 and located between the two connecting members 2, the center of the cross plate 82 is connected with the end of the supporting rod 81 away from the cross beam 1, and the two ends of the cross plate 82 are provided with through holes 83. Figure 3 In the embodiment, the supporting rod 81 is installed at the middle position between the two connecting members 2, and the end of the supporting rod 81 away from the cross beam 1 is installed at the center of the cross plate 82, and two through holes 83 are symmetrically arranged at the two ends of the cross plate 82. During hoisting, the two chains of the manual hoist can be connected with the two connecting members 2 by passing through the two through holes 83, respectively, and the chains of the manual hoist are limited by the guiding assembly 8, so as to avoid serious swinging of the chains during lifting.

[0049] In summary, compared with the prior art, the present application has the following beneficial effects:

[0050] 1. During use, the two sliding blocks are driven to move by rotating the bidirectional screw rod, the two sliding sleeves are driven to move by the two sliding blocks, so that the first connecting rod and the second connecting rod are moved closer to each other, and the motor or other electromechanical equipment is limited and fixed by the positioning assembly and the pressing assembly. The device can quickly fix motors of different sizes, thereby improving the hoisting efficiency and making the device have high versatility.

[0051] 2. During use, the chains of the manual hoist are hung on the two connecting members (hanging rings) by passing through the guiding assembly, respectively, and the chains of the manual hoist are limited by the guiding assembly, thereby ensuring the stability of hoisting.
