Description

A kind of standard section introduction trolley and track

technical field

The invention belongs to the field of ground jointing devices for electric poles and tower cranes, in particular to a trolley and a track for introducing standard joints.

Background technique

In the current electric pole and tower crane operations, ground jacking and ground replacement of standard joints are more and more widely used. The usual method is to use lifting trolleys to directly lift the standard joints for adding joints, which has the disadvantages of high labor intensity and The standard section is difficult to put in place, and the height of the introduced track cannot be adjusted to follow the height of the ground.

Chinese patent document CN205132976U discloses an auxiliary device for the introduction of standard joints. When in use, the standard joints to be imported are placed on the introduction trolley, and the trolley is on the introduction beam, and the long hook is manually operated by a person to pull the standard joint to a predetermined position. , to complete the introduction of the standard section, the long-distance operation reduces the safety hazards of high-altitude operations during the introduction of the standard section; however, the device is mainly adjusted by the long hook until the introduction of the standard section enters the predetermined position, but the long hook control will greatly reduce the safety hazards of the standard section. The control ability of the joints prolongs the time required for the standard joints to be in place, which increases the labor intensity. In addition, the actual construction ground is often uneven, and the device is only suitable for flat ground.

Therefore, there is an urgent need for a standard joint introduction device for ground joints of electric poles and tower cranes, which can reduce labor intensity, adapt to different grounds, and at the same time, allow the standard joint to enter a predetermined position.

Contents of the invention

The object of the present invention is to solve the problems existing in the prior art, and provide a trolley and track for introducing a standard section, which reduces the labor intensity and the difficulty of putting the standard section in place, and at the same time, can adapt to uneven ground conditions.

In order to achieve the above object, the technical scheme adopted in the present invention is:

A standard section lead-in trolley and track, including a lead-in track, a lead-in trolley and a lead-in track support seat, the lead-in trolley is placed on the lead-in track, and the lead-in track support seat is located at the bottom of the lead-in track as a support; The lead-in track support seat includes a support seat, adjustable push rods and adjustment nuts located on both sides of the support seat. The adjustable push rod includes a fixedly connected support rod and a top plate. In contact with the bottom of the introduction track, the support rod is connected with the support base through an adjustment nut, and the vertical height of the support rod is adjustable.

When using the standard section of the present invention to introduce the trolley and the track, first adjust the height of the adjustable ejector rod through the adjustment nut according to the height of the ground, so that the height of the introduction track is suitable, the introduction trolley is placed on the introduction track, and the standard section is placed on the introduction trolley Then the introduction trolley is pulled by the introduction track to wait for the introduction of the standard section to move to the predetermined position. After being in place, the standard section is hoisted, the introduction trolley is separated from the standard section, and the introduction trolley can move to the initial position along the introduction track to continue to introduce the next Festival Standard Festival. The invention is suitable for adding joints to the ground of electric power poles and tower cranes, which reduces labor intensity and difficulty in positioning standard joints. At the same time, the height of the introduced track can be adjusted to adjust the height of the ground, thereby adapting to uneven ground conditions.

Further, the introduction trolley adopts a roller structure, including fixedly connected rollers and a trolley frame, the rollers can slide along the introduction track, and the rollers are provided with rims. When the imported trolley travels, the rim limit is used to prevent the imported trolley from derailing.

Furthermore, a positioning plate is provided on the trolley frame. The positioning plate is used to locate the position of the standard section to be introduced to ensure the accuracy of the standard section in place.

Further, the introduction track adopts an integrated structure, including two parallel slide rails and a frame connecting the two slide rails.

Furthermore, anti-derailment stoppers are provided at the four corners of the introduction track. The anti-derailment limiter can prevent the imported trolley from derailing, which improves the safety.

Further, the top plate includes an arc-shaped bottom plate and a limit block. The limit block can limit the position of the lead-in track to prevent its position from shifting during the movement of the lead-in trolley and cause inaccurate positioning.

Further, there are two lead-in rails, two lead-in rails are placed side by side, one lead-in trolley, four lead-in track support seats, and every two lead-in track support seats serve as a support for one lead-in track. The lead-in track and the support seat of the lead-in track can be used in combination according to the requirements of the situation. When there are two lead-in tracks, it can be adapted to a standard section with a larger specification.

Compared with prior art, the beneficial effect of the present invention is:

1. The trolley and track introduced in the standard section of the present invention are suitable for use in electric power poles and tower cranes to add joints to the ground, which reduces labor intensity and difficulty in positioning the standard section.

2. In the present invention, the height of the lead-in track can be adjusted to the height of the ground through the adjustable ejector rod, so as to adapt to the unevenness of the ground.

3. The present invention has a simple structure and is easy to assemble and disassemble. The lead-in track and the support seat of the lead-in track can be used in combination according to the requirements of the situation, and the scope of application is wider.
