Abstract

The drive chain changes the tool. The existing method for replacing the broken pin of the speed reducer and the motor on the coupling falls behind, the broken pin is still knocked out through a hair clasp, the maintenance space is narrow, the expansion of tools is not facilitated, and the damage to the coupling is easily caused in the maintenance process. The utility model discloses the constitution includes: i-shaped board (6), channel-section steel (3), screw rod (2) and two symmetrical arrangement's V-arrangement hook plate (4), the screw rod pass the channel-section steel with I-shaped board rotatable coupling, the screw rod with channel-section steel screw-thread fit, the V-arrangement hook plate one end with the channel-section steel articulated, the other end passes the I-shaped board, every the tip of V-arrangement hook plate all have arc opening (7). The utility model is used for the driving chain is changed.

Description

Transmission chain replacing tool

Technical Field

The utility model relates to a driving chain replacement tool.

Background

Transmission chain transmission is adopted outside the existing buried scraper type coal feeder, phenomena such as abrasion and fracture often occur to a transmission chain, and in the transmission chain replacement process, a maintainer uses equipment such as iron wires and steel wire ropes to connect the transmission chain end to end and then carries out connecting pin connection work.

Disclosure of Invention

The utility model aims at providing a driving chain change instrument.

The above purpose is realized by the following technical scheme:

the utility model provides a driving chain changes instrument, its constitution includes I-shaped board, channel-section steel, screw rod and two symmetrical arrangement's V-arrangement hook plate, the screw rod pass the channel-section steel with I-shaped board rotatable coupling, the screw rod with channel-section steel screw-thread fit, the V-arrangement hook plate one end with the channel-section steel articulated, the other end passes the I-shaped board, every the tip of V-arrangement hook plate all have the arc opening.

The transmission chain replacing tool is characterized in that two ends of the I-shaped plate are connected with fixing bolts.

Has the advantages that:

1. the utility model discloses a handle is pulled in the rotation for the screw rod rotates, drives the channel-section steel motion, makes two V-arrangement hook plates realize pressing from both sides tightly gradually and loosen, adapts to the installation work of on-the-spot not unidimensional driving chain.

2. The utility model discloses greatly having saved manpower and materials, having shortened operating time, improving work efficiency, can having let equipment faster input operation, original working method is by the staff manual going on, if iron wire, wire rope fracture suddenly, probably cause the injury to the staff, use this kind of risk can be avoided to this instrument.

Description of the drawings:

fig. 1 is a top view of the present invention;

FIG. 2 is a front view of the present invention;

FIG. 3 is a schematic structural view of the present invention in use;

in the figure: 1. a spanner handle; 2. a screw; 3. channel steel; 4. a V-shaped hook plate; 5. fixing the bolt; 6. i-shaped plates; 7. an arc-shaped gap.

The specific implementation mode is as follows:

example 1:

the utility model provides a driving chain changes instrument, its constitution includes I-shaped board 6, channel-section steel 3, screw rod 2 and two symmetrical arrangement's V-arrangement hook plate 4, the screw rod pass the channel-section steel with I-shaped board rotatable coupling, the screw rod with channel-section steel screw-thread fit, the V-arrangement hook plate one end with the channel-section steel articulated, the other end passes the I-shaped board, every the tip of V-arrangement hook plate all have arc opening 7.

Example 2:

according to the tool for replacing the transmission chain in the embodiment 1, two ends of the I-shaped plate are connected with the fixing bolts 5.

The working principle is as follows: when using, as shown in fig. 3, insert two V-arrangement hook plates respectively in the two chain holes of driving chain head and the tail, rotate and pull 1 for the screw rod rotates, and screw rod and channel-section steel threaded connection drive the channel-section steel upward movement, make the distance between two V-arrangement hook plates reduce gradually, and the driving chain head and the tail receives opposite direction power and slowly is close to, when the pinhole is relative, can carry out the pin connection, thereby accomplishes the whole work of changing of driving chain.

Claims

1. A kind of driving chain changes tools, its characteristic is: the V-shaped hook plate comprises an I-shaped plate, channel steel, a screw and two symmetrical hook plates, wherein the screw penetrates through the channel steel and the I-shaped plate in a rotatable connection mode, the screw is in threaded fit with the channel steel, one end of the V-shaped hook plate is hinged to the channel steel, the other end of the V-shaped hook plate penetrates through the I-shaped plate, and each end of the V-shaped hook plate is provided with an arc opening.

2. The drive chain changing tool of claim 1, wherein: and two ends of the I-shaped plate are connected with fixing bolts.
