Description

Technical Field

[0001] This utility model belongs to the field of railway track fastener installation technology, specifically relating to a railway track fastener installation device. Background Technology

[0002] At the construction site, due to the complex working environment, the installation equipment needs to be frequently adjusted to align with different rail fastener bolts. However, the current electric bolt tightening machine has an unreasonable structural design and lacks convenient auxiliary positioning devices during transportation, which causes operators to spend a lot of time and energy to accurately adjust its position, seriously affecting the installation progress.

[0003] The existing device cannot tighten two bolts at the same time. Rail fasteners are usually fixed by multiple bolts, and only one bolt can be tightened at a time. This means that to complete the installation of a set of fasteners, multiple manual adjustments and tightenings are required. This operation method is not only inefficient, but also makes it difficult to ensure the consistency of the tightening torque of each bolt due to multiple manual operations, thereby affecting the installation quality of the rail fasteners and increasing safety hazards during railway operation.

[0004] Therefore, in response to the problem that the existing railway track fastener installation device has difficulties in handling, positioning and adjusting the electric bolt tightening machine and cannot tighten two bolts at the same time, resulting in the need for multiple manual adjustments and tightenings of the track fastener bolts during installation, a railway track fastener installation device can be designed. Utility Model Content

[0005] To overcome the problem that existing railway track fastener installation devices, due to the difficulty in handling, positioning, and adjusting the electric bolt tightening machine and the inability to tighten two bolts simultaneously, require multiple manual adjustments and tightenings of the track fastener bolts during installation.

[0006] The technical solution of this utility model is as follows: a railway track fastener installation device, including a shell assembly, an electric bolt tightening machine assembly for railway tracks, a height adjusting screw, and a positioning assembly; the electric bolt tightening machine assembly for railway tracks is installed inside the shell assembly; a height adjusting screw is installed on one side of the lower end of the electric bolt tightening machine assembly for railway tracks; positioning assemblies are installed on both the front and rear sides of the electric bolt tightening machine assembly for railway tracks; the shell assembly includes a housing, an electrical control box, and a lifting handle; the electric bolt tightening machine assembly for railway tracks includes an electric bolt tightening machine and a bolt tightening sleeve; the positioning assembly includes a track limiting clamp and a bracket.

[0007] Preferably, the entire device is moved to the position directly above the rail fastener installation by hand, and then the rail limiting clamp is placed on the rail to hold it in place. The height adjusting screw is then adjusted so that the four corners of the bracket are supported on the ground, thus completing the downward clamping and fixing of the rail. At the same time, the bolt tightening sleeve is inserted into the bolt of the fastener below. The control box controls the electric bolt tightening machine to drive the bolt tightening sleeve and the lower bolt to rotate. The hydraulic feed structure of the electric bolt tightening machine pushes downward, thereby realizing the quick assembly function of the fastener. This solves the problem of existing railway rail fastener installation devices, which have difficulties in handling, positioning and adjusting the electric bolt tightening machine and cannot tighten two bolts at the same time, resulting in the need for multiple manual adjustments and tightenings for the installation of rail fastener bolts.

[0008] Preferably, the housing is equipped with an electric bolt tightening machine, and two sets of electric bolt tightening machines are provided; an electrical control box is provided on the front face of the housing, and the electrical control box is electrically connected to the electric bolt tightening machine assembly for railway tracks.

[0009] Preferably, the lower end of the electric bolt tightening machine is provided with a bolt tightening sleeve, and the electric bolt tightening machine drives the bolt tightening sleeve to rotate and connect.

[0010] Preferably, a track limiting clamp is provided between the two bolt tightening sleeves; a height adjusting screw is provided in front of the track limiting clamp.

[0011] Preferably, the height adjusting screw is connected to the housing thread lifting transmission, and the lifting movable end of the height adjusting screw is connected to the housing ball bearing of the track limit clamp.

[0012] Preferably, the track limiting clamp is provided with brackets at both the front and rear ends, and the brackets are integrally formed with the housing.

[0013] Preferably, a lifting handle is provided at the lower front end of the housing, and the lifting handle is fixedly connected to the housing.

[0014] The beneficial effects of this utility model are:

[0015] 1. Existing railway track fastener installation devices suffer from difficulties in handling, positioning, and adjusting the electric bolt tightening machine, and the inability to tighten two bolts simultaneously, resulting in the need for multiple manual adjustments and tightenings during track fastener installation. The new device solves this problem by manually lifting and pulling the device to a position directly above the track fastener installation area. The track clamp is then placed on the track to hold it in place. The height adjustment screw is adjusted so that the four corners of the support are supported on the ground, thus securing the track. Simultaneously, the bolt tightening sleeve is inserted into the lower fastener bolt. The control box controls the electric bolt tightening machine to rotate the bolt tightening sleeve and the lower bolt. The hydraulic feed mechanism of the electric bolt tightening machine pushes downwards, enabling rapid fastener assembly. This solution addresses the problem of existing railway track fastener installation devices where the electric bolt tightening machine is difficult to handle, position, and adjust, and cannot tighten two bolts simultaneously, requiring multiple manual adjustments and tightenings during track fastener installation.

[0016] 2. Through the setting of the electrical control box, the tightening degree of the bolts can be freely set, so that the fastener bolts on both sides of the track can be tightened synchronously and to the same depth, which greatly improves the installation efficiency of track fasteners.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] During operation, the entire device is moved to the position directly above the rail fastener installation area by holding the lifting handle 103. Then, the rail limiting clamp 401 is placed on the rail to clamp it. The height adjusting screw 3 is then adjusted so that the four corners of the bracket 402 are supported on the ground, thus completing the downward clamping and fixing of the rail. At the same time, the bolt tightening sleeve 202 is inserted into the bolt for the fastener below. The control box 102 controls the electric bolt tightening machine 201 to rotate the bolt tightening sleeve 202 and the bolt at the lower end.

[0027] Through the above steps, the entire device is moved to the position directly above the rail fastener installation by holding the lifting handle 103. Then, the rail limiting clamp 401 is placed on the rail to clamp it. The height adjusting screw 3 is then adjusted so that the four corners of the bracket 402 are supported on the ground, thus completing the downward clamping and fixing of the rail. At the same time, the bolt tightening sleeve 202 is inserted into the bolt of the fastener below. The control box 102 controls the electric bolt tightening machine 201 to drive the bolt tightening sleeve 202 and the bolt at the lower end to rotate. The hydraulic feed structure of the electric bolt tightening machine 201 pushes downward to realize the quick assembly function of the fastener. This avoids the problem of existing railway rail fastener installation devices, which have difficulty in moving, positioning and adjusting the electric bolt tightening machine and cannot tighten two bolts at the same time, causing the installation of rail fastener bolts to require multiple manual adjustments and tightenings.
