Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of hoisting machinery equipment, and particularly relates to a tire crane speed reducer base adjusting device. BACKGROUND

[0002] The statements herein merely provide background technology related to the present disclosure, and do not necessarily constitute prior art.

[0003] In the trolley running mechanism of a conventional tire crane, the driving part is usually vertically installed, the driving motor is fixed on the driving frame through a base, the upper part of the speed reducer is rigidly connected with the mounting bracket, and the lower part is fixed to the frame through a bolt assembly. In order to adapt to the tensioning requirement of the driving chain, a long circular hole mounting position is usually arranged on the frame, and the height of the speed reducer in the vertical direction is finely adjusted by means of the position adjustment of the bolt in the long circular hole. In actual application, due to the superposition of welding deformation of the driving frame, casting tolerance of the speed reducer and machining error of the mounting bracket, a certain error will occur between the actual installation height of the speed reducer and the theoretical height. The existing adjustment method needs to loosen the connecting bolts on the bases to displace the bases as a whole, and the secondary deviation of the axis of the speed reducer and the driving motor is easily caused in the operation, which causes poor meshing of the chain. This leads to abnormal wear, chain breakage and even failure of the driving mechanism in the subsequent use process. In addition, when the deviation is too large, the technician has to disassemble the speed reducer for gasket compensation, and the adjustment efficiency is low. CONTENT OF THE UTILITY MODEL

[0023] As Figures 1-4 shown, the embodiment provides a tire crane reducer base adjustment device, which comprises a sliding assembly and an adjustment assembly. Through the coordinated action of the sliding assembly and the adjustment assembly, fine adjustment of the installed reducer 6 in the vertical height direction is realized.

[0024] As Figure 1 shown, the sliding assembly and the adjustment assembly are both vertically arranged on the mounting bracket of the tire crane. The adjustment assembly is arranged below the sliding assembly, and the sliding assembly is connected with the base of the reducer 6 through bolts. The sliding assembly is composed of a driving carriage 1 vertically arranged along the mounting bracket and a sliding plate 2 arranged between the driving carriage 1 and the base of the reducer 6. Through the sliding plate 2, friction can be effectively reduced, so that the sliding assembly is smoother during adjustment.

[0025] As Figure 2 and Figure 3 shown, the interval distance of the sliding groove is consistent with the interval distance of the bolt holes on the base of the reducer 6; the interval distance of the threaded holes is consistent with the interval distance of the bolt holes on the base of the reducer 6. The driving carriage 1 is provided with a long circular hole-shaped sliding groove, the sliding plate 2 is provided with threaded holes, and the sliding plate 2 is provided with two groups of support seats consistent with the length of the base of the reducer 6. The threaded holes pass through the support seats and are arranged. The support seat and the sliding plate 2 are connected by welding.

[0026] Specifically, the long circular hole-shaped sliding groove provided on the driving carriage 1 forms an axial sliding pair with the sliding plate 2. In combination with the bolt connection structure of the sliding plate 2 support seat and the base of the reducer 6, fine adjustment of the installed reducer 6 in the vertical height direction is realized. Through the sliding of the sliding plate 2 in the sliding groove, the transverse misalignment between the base of the reducer 6 and the driving carriage 1 is eliminated, and the smooth installation of the bolt assembly is ensured. This process does not require disassembly of any parts, and fine adjustment can be achieved by loosening the fixing bolts of the sliding plate 2.

[0027] At the same time, through the support seat, the contact area between the base of the reducer 6 and the driving carriage 1 can be increased. Even if the bolt breaks in an extreme case, the sliding plate 2 can still be temporarily positioned through the planar friction between the support seat and the driving carriage 1.

[0028] Moreover, the sliding plate 2 and the driving carriage 1 are designed in a split type, and the two are connected through standard bolts. When the sliding groove is worn due to long-term use, the sliding plate 2 can be replaced alone without the need to disassemble the driving carriage 1 as a whole.

[0029] As Figure 1 and Figure 4As shown, the adjusting assembly is composed of a welded stopper 5, an adjusting bolt 3 and an adjusting nut 4, the welded stopper 5 is arranged below the slide plate 2 and connected with the driving support, the welded stopper 5 is provided with a through hole, the adjusting bolt 3 passes through the through hole and is connected with the adjusting nut 4; the adjusting bolt 3 is in contact with the slide plate 2 and located at the symmetric center line of the lower side edge of the slide plate 2; the welded stopper 5 is welded with the driving support.

[0030] Specifically, the rigid connection of the welded stopper 5 and the driving support not only provides a stable support base for the adjusting bolt 3, but also forms a unique shear-resistant protection structure through the clearance fit between the internal through hole and the adjusting bolt 3; when the driving mechanism bears the transverse impact generated by the sudden stop of the cart or the sudden change of the load, the welded stopper 5 can conduct the lateral force received by the slide plate 2 to the driving cart frame 1 through the friction of the contact surface, so as to avoid that the adjusting bolt 3 bears the non-axial load.

[0031] Working principle of the utility model:

[0032] The long circular hole-shaped sliding groove on the driving cart frame 1 forms an axial sliding pair with the slide plate 2, when the mounting plane of the reducer 6 is horizontally offset due to manufacturing error, the connecting bolt between the slide plate 2 and the driving cart frame 1 can be loosened first, the slide plate 2 is pushed to move along the horizontal direction by using the guiding effect of the sliding groove, and the misalignment between the reducer 6 base and the driving cart frame 1 is eliminated; the two groups of support seats on the slide plate 2 are fixedly connected with the slide plate 2 through welding, the threaded holes are accurately positioned with the bolt holes of the reducer 6 base, and the coaxiality of the reducer 6 and the driving motor is ensured during the sliding process.

[0033] Although the specific embodiments of the present disclosure are described above with reference to the drawings, it is not a limitation on the protection scope of the present disclosure, and those skilled in the art should understand that various modifications or changes made on the basis of the technical solutions of the present disclosure without creative labor are still within the protection scope of the present disclosure.
