Description

Technical Field

[0001] This utility model relates to the field of crane maintenance technology, and in particular to a clamping and fixing device for crane maintenance. Background Technology

[0002] Cranes are a type of modern lifting equipment. They are important pieces of mechanized and automated equipment and are widely used in major industries such as ports, docks, steel, and chemicals. To ensure the long-term stable operation of cranes, proper maintenance and repair are essential.

[0003] When repairing a crane, if it is necessary to clamp and fix some shafts and turntables, the existing fixing clamps usually fix the device during the crane repair process by rotating the pressure roller and adjusting the distance between the two clamping surfaces.

[0004] In the aforementioned prior art, the adjustment distance between the two clamping surfaces of the fixing frame is limited. During the tightening and fixing process, the operator needs to rotate the tightening roller multiple times, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping and fixing device for crane maintenance, which solves the problem that the adjustment distance between the two clamping surfaces of the fixing frame is limited in the prior art, and that the operator needs to rotate the clamping roller multiple times during the clamping and fixing process, which is time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides a clamping and fixing device for crane maintenance, including a positioning and fixing frame. The positioning and fixing frame and the sliding fixing frame are slidably connected by a plug. A limiting block is provided on the upper side of the plug. The limiting block is adapted to the sliding groove on the inner side of the positioning and fixing frame. An adjusting rod is provided inside the limiting block. An adjusting block is provided inside the sliding fixing frame. The adjusting block and the adjusting rod are provided with mutually adapted threads. The adjusting rod is driven by a stepper motor. A manual clamping component is provided on the upper side of the positioning and fixing frame. A supporting component is provided on the upper side of the sliding fixing frame.

[0007] The positioning and fixing frame is further provided with a threaded sleeve, which is fixedly installed on the upper inner wall of the positioning and fixing frame and is threadedly adapted to the manual tightening component.

[0008] The manual clamping assembly includes a manual lever, a clamping lever, and a clamping block. The clamping block is fixedly disposed at one end of the clamping lever, the manual lever is fixedly disposed at the other end of the clamping lever, and the clamping lever is threadedly connected to the threaded sleeve.

[0009] The abutment assembly includes a mounting block, two abutment spring posts, and an abutment block. The abutment block is fixedly disposed on the inner side of the mounting block by the two abutment spring posts, and the mounting block is fixedly disposed on the upper end of the sliding fixing frame.

[0010] The outer surfaces of both the supporting block and the pressing block are coated with an anti-slip coating.

[0011] The advantages of this invention, which provides a clamping and fixing device for crane maintenance, are as follows:

[0012] The stepper motor drives the threaded transmission between the adjusting rod and the adjusting block to achieve electric coarse adjustment of the distance between the positioning fixing frame and the sliding fixing frame. The adjustment range is not limited by the stroke of the traditional clamping roller and can be adapted to crane shafts, turntables and other parts of different sizes. The coarse adjustment of the distance is completed by electric drive, eliminating the need for repeated manual rotation of the clamping rod. Only manual fine adjustment is required to achieve precise clamping, which greatly reduces manual operation steps and labor intensity, and improves the efficiency of crane maintenance.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-3 ,in Figure 1This is a schematic diagram of the overall structure of a clamping and fixing device for crane maintenance according to this utility model. Figure 2 This is a left view of a clamping and fixing device for crane maintenance according to this utility model. Figure 3 This is the utility model Figure 2 A sectional view along line AA.

[0020] This utility model provides a clamping and fixing device for crane maintenance, including a positioning and fixing frame 1. The positioning and fixing frame 1 and the sliding fixing frame 2 are slidably connected by a plug block 3. A limiting block 4 is provided on the upper side of the plug block 3. The limiting block 4 is adapted to the sliding groove 5 on the inner side of the positioning and fixing frame 1. An adjusting rod 6 is provided inside the limiting block 4. An adjusting block 7 is provided inside the sliding fixing frame 2. The adjusting block 7 and the adjusting rod 6 are provided with adapted threads at their contact points. The adjusting rod 6 is driven by a stepper motor 8. A manual clamping component 9 is provided on the upper side of the positioning and fixing frame 1, and a retaining component 9 is provided on the upper side of the sliding fixing frame 2. Specifically, the insert block 3 is integrally formed on the bottom of the sliding fixing frame 2 and extends along the length direction of the positioning fixing frame 1. The middle part of the adjusting rod 6 that fits with the limiting block 4 has an external thread structure. The inner hole of the adjusting block 7 has an internal thread that matches the external thread of the adjusting rod 6. The adjusting rod 6 and the adjusting block 7 are connected by threaded engagement. The adjusting rod 6 is driven to rotate by the stepper motor 8. The threaded transmission drives the adjusting block 7 and the sliding fixing frame 2 to move along the length direction of the positioning fixing frame 1, thereby realizing the electric adjustment of the distance between the two fixing frames.

[0021] The positioning and fixing frame 1 is also provided with a threaded sleeve 11; the manual clamping assembly 9 includes a manual lever 12, a clamping lever 13, and a clamping block 14. The clamping lever 13 is threadedly connected to the threaded sleeve 11. The abutment assembly 10 includes a mounting block 15, two abutment spring posts 16, and an abutment block 17. The outer surfaces of the abutment block 17 and the clamping block 14 are coated with an anti-slip coating. Specifically, the outer surface of the clamping lever 13 is provided with an external thread, which engages with the internal thread of the threaded sleeve 11. When the operator rotates the manual lever 12, the clamping lever 13 can be moved axially along the threaded sleeve 11, thereby adjusting the distance between the clamping block 14 and the abutment block 17 to achieve precise clamping.

[0022] In this embodiment, based on the dimensions of the crane component to be fixed, the stepper motor 8 is started to drive the adjusting rod 6 to rotate. The adjusting rod 6, through threaded transmission with the adjusting block 7, drives the sliding fixing frame 2 to slide along the slide groove 5 of the positioning fixing frame 1, adjusting the distance between the positioning fixing frame 1 and the sliding fixing frame 2 so that the component can be smoothly placed between the two fixing frames. The stepper motor 8 is then turned off, the manual lever 12 is held, and the clamping lever 13 is rotated to move along the threaded sleeve 11 axially toward the abutment block 17, causing the clamping block 14 to gradually approach the component. When the clamping block 14 contacts the surface of the component, the manual lever 12 is slowly rotated until the component is clamped and fixed by the clamping block 14 and the abutment block 17. At this time, the abutment spring column 16 is compressed and undergoes elastic deformation, forming a buffer clamping force on the component.
