Description

Technical Field

[0001] This utility model relates to the field of screw compressor technology, specifically to a traction and hoisting integrated screw compressor. Background Technology

[0002] Mobile air compressors are widely used in industries such as transportation, mining, water conservancy, shipbuilding, urban construction, and military. They are primarily used to power air-consuming equipment for drilling, shotcreting, and impact operations. During operation, the compressors often need to be moved, requiring equipment (such as forklifts or excavators) to pull a tow bar to move them. After the work is completed at the work site, the machine needs to be hoisted onto transport equipment.

[0003] Current mobile screw compressors typically have a drawbar at the front and a hanger inside. With the drawbar only at one end, turning the machine becomes problematic. Loaders have a large turning radius, and in most situations, towed screw compressors cannot meet the turning requirements.

[0004] Meanwhile, placing the hanger inside the screw compressor will occupy the space of other components inside the screw compressor and affect the machine layout; the opening position of the hoisting hole will affect the strength of the ceiling, and the machine is prone to tilting when there is a single hoisting point, which poses a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to provide a traction and hoisting integrated screw press to solve the technical defects of existing mobile screw presses in traction and hoisting during transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A traction and hoisting integrated screw press includes a machine body with two easily movable and steerable tire assemblies at its bottom. Each tire assembly is movably connected to a traction and hoisting assembly for easy traction or hoisting. The traction and hoisting assemblies are located on both sides of the machine body.

[0008] The traction and lifting assembly includes two side plates on the tire assembly, with a traction and lifting rod fixedly connected between the two side plates. The top of the traction and lifting rod extends to the roof of the machine body, and a through hole is provided on the upper part of the surface of the traction and lifting rod. The traction and lifting rod is detachably connected to the machine body.

[0009] As a further embodiment of this utility model, the traction hoisting rod and the machine body are detachably connected by bolts, and mounting screw holes for bolts to pass through are provided on the upper and lower parts of the traction hoisting rod and the machine body surface.

[0010] As a further embodiment of this utility model, the surface of the body is provided with multiple anti-loss screw holes, which are arranged in a one-to-one correspondence with the mounting screw holes, and the anti-loss screw holes are located on one side of the mounting screw holes.

[0011] As a preferred embodiment of this utility model, the tire assembly includes an axle installed at the bottom of the chassis frame, with tires movably mounted at both ends of the axle, a swinging member between the axle and its two adjacent side plates, and a linkage member between the swinging member and the tire.

[0012] As a further embodiment of this utility model, the swing member includes a swing beam hinged to the middle of the axle surface. One end of the swing beam is hinged to its two adjacent side plates. A support plate is fixedly connected to one end of the bottom of the swing beam. An I-shaped block is fixedly connected to the end of the support plate away from the swing beam. The I-shaped block is movably connected to the tire through a linkage member.

[0013] As a further embodiment of this utility model, the linkage includes two steering tie rods hinged to the I-shaped block, with a steering horn hinged to the end of the steering tie rod away from the I-shaped block. The steering horn is hinged to the end of the axle, and the end of the steering horn away from the steering tie rod is fixedly connected to the tire.

[0014] As a preferred embodiment of this utility model, limit blocks are fixedly connected to both sides of the sway beam, and one end of the limit block can contact the surface of the axle.

[0015] As a preferred embodiment of this utility model, a rubber pad is fixedly connected to the end of the limiting block that is away from the limiting block and faces the axle.

[0016] Compared with existing technologies, this utility model of an integrated traction and hoisting screw conveyor has the following advantages: This utility model changes the usage state by whether or not the rigid connection between the traction and hoisting assembly and the machine body is released. When using the hoisting function, the traction and hoisting assembly is fixed vertically to the machine body to achieve a rigid connection, thus ensuring hoisting strength. When using the traction function, the traction and hoisting assembly is removed from the machine body and placed horizontally to release the rigid connection. When using the traction and hoisting assembly for traction, the linkage between the swinging component and the linkage component drives the tires to rotate, achieving the machine body's steering function. Setting through holes on the traction and hoisting rod changes the hoisting position, which helps improve hoisting stability and the strength of the machine body's roof. Simultaneously, using two traction and hoisting assemblies on the machine body solves the problem of difficulty in turning the machine body around. Attached Figure Description

[0030] See appendix Figures 1-4 As shown in the figure, an embodiment of the present invention provides a traction and hoisting integrated screw press, including a machine body 100, a tire assembly 200 that is easy to move and can be turned, and a traction and hoisting assembly 300 that facilitates traction or hoisting of the machine body 100. Two tire assemblies 200 are symmetrically arranged at the bottom of the base frame of the machine body 100, and a traction and hoisting assembly 300 is provided on each tire assembly 200. The traction and hoisting assembly 300 includes two side plates 310 provided on the tire assembly 200, and a traction and hoisting rod 320 is fixedly connected between the two side plates 310. The top end of the traction and hoisting rod 320 extends to the top of the machine body 100, and a through hole 330 is provided on the upper part of the surface of the traction and hoisting rod 320. The traction and hoisting rod 320 is detachably connected to the machine body 100.

[0031] To ensure lifting strength, the traction lifting rod 320 and the machine body 100 are detachably connected by bolts. The upper and lower parts of the surface of the traction lifting rod 320 and the machine body 100 are provided with mounting screw holes 340 for bolts to pass through. At least two mounting screw holes 340 are provided on the lower part of the surface of the traction lifting rod 320 and the machine body 100. The traction lifting assembly 300 and the machine body 100 are rigidly connected by multiple bolts.

[0032] The surface of the body 100 is provided with multiple anti-loss screw holes 400. The anti-loss screw holes 400 are set in a one-to-one correspondence with the mounting screw holes 340, and the anti-loss screw holes 400 are located on one side of the mounting screw holes 340. Unused screws can be screwed into the inner cavity through the anti-loss screw holes 400 for temporary storage, which can prevent loss and facilitate retrieval.

[0033] In order to achieve contact with the road surface and ensure the mobility of the machine body 100 while supporting the machine body 100, the tire assembly 200 includes an axle 210 installed at the bottom of the chassis of the machine body 100. Tires 220 are movably provided at both ends of the axle 210. A swing member 230 is provided between the axle 210 and its two adjacent side plates 310. A linkage member 240 is provided between the swing member 230 and the tire 220.

[0034] In order to provide an installation base for the linkage component 240 and to enable the traction and hoisting assembly 300 to work in conjunction with the linkage component 240, the swing component 230 includes a swing beam 231 hinged to the middle of the surface of the axle 210 by a pin. One end of the swing beam 231 is hinged to its two adjacent side plates 310 by a pin. A support plate 232 is fixedly connected to one end of the bottom of the swing beam 231. An I-shaped block 233 is fixedly connected to the end of the support plate 232 away from the swing beam 231. The I-shaped block 233 is movably connected to the tire 220 through the linkage component 240.

[0035] To ensure the normal operation of the steering function of the machine body 100, the linkage 240 includes two steering tie rods 241 hinged to the I-shaped block 233 by a pin. The end of the steering tie rod 241 away from the I-shaped block 233 is hinged to a steering horn 242 by a pin. The steering horn 242 is hinged to the end of the axle 210 by a pin. The end of the steering horn 242 away from the steering tie rod 241 is fixedly connected to the tire 220. The linkage 240 can link the swing member 230 and the tire 220, so that the axle 210, the swing member 230 and the linkage 240 form a double rocker structure by a pin. Then, the traction and hoisting assembly 300 drives the swing member 230 to swing around the pin in the middle of the axle 210, which in turn drives the tire 220 to rotate around the pin at the end of the axle 210.

[0036] To prevent the swing component 230 from swinging excessively, both sides of the swing beam 231 are fixedly connected with limit blocks 2311 at an incline. One end of the limit block 2311 can contact the surface of the axle 210, which can limit the left and right swing amplitude of the swing beam 231.

[0037] To prevent structural damage to the sway beam 231 and axle 210 due to impact or friction, a rubber pad 2312 is fixedly connected to the end of the limit block 2311 facing the axle 210 away from the limit block 2311, which can prevent the end of the limit block 2311 from directly contacting the axle 210.

[0038] When using the hoisting function, the traction hoisting rod 320 is connected to the machine body 100 with bolts to ensure a rigid connection between the traction hoisting rod 320 and the machine body 100. At this time, the machine body 100 can be hoisted through the through hole 330.

[0039] When using the traction function, unscrew the bolt from the mounting bolt hole 340 and temporarily screw it into the adjacent anti-loss bolt hole 400. Then rotate the traction lifting rod 320 downwards so that the traction lifting rod 320 is in a horizontal state. At this time, the machine body 100 can be towed by the traction lifting rod 320. During the traction process, the traction lifting rod 320 drives the sway beam 231, the support plate 232 and the I-shaped block 233 to swing around the pin in the middle of the axle 210 through the side plate 310. The I-shaped block 233 drives the steering tie rod 241 to move. The steering tie rod 241 drives the steering horn 242 and the tire 220 to rotate around the pin at the end of the axle 210 to ensure the normal use of the steering function of the machine body 100.

[0040] This utility model embodiment of the integrated traction and hoisting screw press changes its usage state by whether or not the rigid connection between the traction and hoisting assembly 300 and the machine body 100 is released. When using the hoisting function, the traction and hoisting assembly 300 is fixed vertically to the machine body 100 to achieve a rigid connection, thus ensuring hoisting strength. When using the traction function, the traction and hoisting assembly 300 is removed from the machine body 100 and placed horizontally to release the rigid connection. When using the traction and hoisting assembly 300 for traction, it can drive the tire 220 to rotate through the linkage of the swing member 230 and the linkage member 240, thereby realizing the steering function of the machine body 100. The through hole 330 is set on the traction and hoisting rod 320, and changing the hoisting position helps to improve hoisting stability and the roof strength of the machine body 100. At the same time, two traction and hoisting assemblies 300 are used on the machine body 100, thereby solving the problem of difficulty in turning the machine body 100 around.
