Description

Technical Field

[0001] The utility model relates to the technical field of truck-mounted cranes, in particular to a railway truck-mounted crane. Background Art

[0002] A truck-mounted crane is a device that uses a hydraulic lifting and telescopic system to achieve the lifting, rotation and hoisting of goods. It is usually installed on a truck.

[0003] Existing truck-mounted cranes are fixed to vehicles through mounting holes and bolts. Generally, the crane is first lifted as a whole by an external crane, and then aligned with the mounting holes on the vehicle, and then the bolts are installed inside the mounting holes and fixed. However, this method requires constant position adjustment to align the positions of the mounting holes on the crane and the vehicle with each other, which wastes a lot of time and makes the installation process more cumbersome.

[0004] Therefore, a railway truck-mounted crane is proposed. Summary of the invention

[0005] The utility model aims to provide a railway truck-mounted crane to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a railway truck crane, comprising a bottom plate, a gear ring is installed on the upper surface of the bottom plate, an annular limiting plate is provided above the gear ring, limiting teeth are provided on the upper and lower surfaces of the annular limiting plate, and the lower limiting teeth are meshed and connected with the gear ring;

[0007] A plurality of fixed covers are symmetrically mounted on the outer side of the annular limiting plate, and fixed teeth are arranged above the inner side wall of the fixed cover, and the fixed teeth are meshed and connected with the limiting teeth above;

[0008] A cover body is installed in the middle of the annular limiting plate, and a base for fixing the crane is installed on the upper surface of the cover body.

[0009] Preferably, a column is installed on the base.

[0010] Preferably: a telescopic arm is installed at the end of the column.

[0011] Preferably: a hook is installed at the end of the telescopic arm.

[0012] Preferably, the four corners of the bottom plate are each provided with a third threaded hole for fixing the position of the bottom plate.

[0013] Preferably, first threaded holes are evenly formed on the bottom of the fixing cover.

[0014] Preferably, the upper surface of the bottom plate is evenly provided with second threaded holes, and the positions of the second threaded holes correspond to those of the first threaded holes.

[0015] Preferably: a limiting cylinder is installed in the middle of the upper surface of the bottom plate, and the cover body is located outside the limiting cylinder.

[0016] Compared with the prior art, the beneficial effect of the utility model is that the limiting work of the crane can be quickly completed by the engagement of the limiting teeth on the annular limiting plate with the gear ring and the fixed teeth, and then the position of the fixed cover is fixed by bolts to complete the fixing work of the annular limiting plate, thereby eliminating the process of aligning the mounting holes and saving a lot of time.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Embodiment 1

[0024] See also Figure 1-4 The utility model provides a technical solution: a railway truck crane, comprising a bottom plate 1, a gear ring 8 is installed on the upper surface of the bottom plate 1, an annular limiting plate 2 is arranged above the gear ring 8, and limiting teeth 9 are arranged on the upper and lower surfaces of the annular limiting plate 2, and the lower limiting teeth 9 are meshed and connected with the gear ring 8;

[0025] A plurality of fixed covers 3 are symmetrically mounted on the outer side of the annular limiting plate 2. The number of the fixed covers 3 is two, and the shape of the fixed covers 3 is semicircular. A fixed tooth 11 is provided above the inner side wall of the fixed cover 3, and the fixed tooth 11 is meshed and connected with the limiting tooth 9 above.

[0026] A cover body 10 is installed in the middle of the annular limiting plate 2, and a base 4 for fixing the crane is installed on the upper surface of the cover body 10.

[0027] like Figure 1 and Figure 2 As shown: a column 5 is installed on the base 4, a telescopic arm 6 is installed at the end of the column 5, and a hook 7 is installed at the end of the telescopic arm 6; through the above arrangement, the column 5 fixes and supports the position of the telescopic arm 6, and the telescopic arm 6 can be extended under the control of the hydraulic cylinder to lift goods at different positions.

[0028] like Figure 3 and Figure 4 As shown: the four corners of the bottom plate 1 are each provided with a third threaded hole 14 for fixing the position of the bottom plate 1; through the above arrangement, the bottom plate 1 can be fixed to the vehicle body through the third threaded hole 14, which is convenient for fixing the crane.

[0029] like Figure 3 and Figure 4 As shown: the bottom of the fixed cover 3 is evenly provided with a first threaded hole 12, and the upper surface of the base plate 1 is evenly provided with a second threaded hole 13, and the position of the second threaded hole 13 corresponds to the position of the first threaded hole 12; through the above arrangement, the position of the fixed cover 3 can be fixed by the cooperation between the first threaded hole 12 and the second threaded hole 13, so that the position of the annular limit plate 2 can be limited and fixed by the fixed cover 3.

[0030] like Figure 4 As shown: a limiting cylinder 15 is installed in the middle of the upper surface of the base plate 1, and the cover body 10 is located on the outside of the limiting cylinder 15; through the above arrangement, the limiting cylinder 15 can perform preliminary limiting work on its position when the annular limiting plate 2 is placed, so as to facilitate the meshing work between the limiting teeth 9 and the gear ring 8.

[0031] Embodiment 2

[0032] A railway truck crane comprises a bottom plate 1, a gear ring 8 is mounted on the upper surface of the bottom plate 1, an annular limiting plate 2 is arranged above the gear ring 8, limiting teeth 9 are arranged on the upper and lower surfaces of the annular limiting plate 2, and the lower limiting teeth 9 are meshed and connected with the gear ring 8;

[0033] A plurality of fixed covers 3 are symmetrically mounted on the outer side of the annular limiting plate 2. A fixed tooth 11 is disposed above the inner wall of the fixed cover 3. The fixed tooth 11 is meshed and connected with the limiting tooth 9 above.

[0035] The number of fixed covers 3 is three or more, and the shape of the fixed covers 3 is fan-shaped. The three fan-shaped fixed covers 3 can more conveniently fix the position of the annular limit plate 2. When the installation position of this device is relatively narrow, the semicircular fixed cover 3 may not be able to penetrate into the installation position, and then the shape of the fixed cover 3 is changed to a fan-shaped shape, reducing the surface area of ​​each fixed cover 3, so that the fixed cover 3 can penetrate into the narrow position to complete the fixation of the position of the annular limit plate 2.

[0036] Working principle: When it is necessary to install the crane, first lift the crane body and the annular limit plate 2 through an external crane, then move the annular limit plate 2 to the top of the bottom plate 1, and make the cover body 10 be sleeved on the outside of the limit tube 15, and then with the falling process, the limit teeth 9 and the gear ring 8 below the annular limit plate 2 are meshed with each other, and then the fixed cover 3 is placed above the annular limit plate 2, and the upper limit teeth 9 are meshed with the fixed teeth 11 on the inner side of the fixed cover 3, and then the fixed cover 3 is fixed to the bottom plate 1 by bolts, and the position of the annular limit plate 2 is fixed by the fixed cover 3, thereby completing the fixing work of the crane.
