Description

Technical Field

[0001] The utility model relates to the technical field of gantry crane installation and construction, in particular to a track foundation of a gantry crane. Background Art

[0002] Gantry crane is the most commonly used lifting equipment on construction sites. It is a tool used to lift steel bars, concrete, pipes and other materials used in construction. It is an indispensable equipment on the construction site.

[0003] Open cut method is the most commonly used construction method for subway stations. This construction method has a short construction period, saves costs, and has a large working area. This construction method will also use a gantry crane to assist in on-site construction. In order to allow the gantry crane to move normally, track support beams are usually laid on the standard section crown beam retaining wall to assist the movement of the gantry crane.

[0004] However, during the construction process at the construction site, due to terrain factors, the crown beam retaining wall will have a special-shaped expansion section. At this time, the track support beam cannot be directly laid on the crown beam retaining wall. The existing solution is to cast a corbel on the side wall of the crown beam retaining wall so that the track support beam of the special-shaped expansion section matches the track support beam at the vertical standard section to form a horizontal line. However, the supporting corbel of each special-shaped expansion section needs to be designed separately, and the construction efficiency is low. Summary of the invention

[0005] In order to solve the problem that each supporting corbel of the existing special-shaped expansion section needs to be designed separately, the utility model proposes a track foundation for a gantry crane, by adding an extension part at the end of the second supporting part in the first supporting body, so that the track support beam at the special-shaped expansion section and the track support beam at the vertical standard section form a horizontal line, and it is only necessary to change the length of the extension part to ensure that the track support beam of the special-shaped expansion section and the track support beam at the vertical standard section match to form a horizontal line, so that the gantry crane can operate normally from the beginning to the end of the construction, thereby improving the on-site operation efficiency.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a track foundation of a gantry crane, fixed to one side of a crown beam retaining wall, including a first support body and a second support body, the first support body includes a first support part and a second support part, the first support part is placed in a mounting groove provided in the side wall of the crown beam retaining wall and is fixedly connected to the crown beam retaining wall, the second support part is fixedly connected to an extension part at one end away from the first support part, the extension part abuts against the outer side of the second support part, the second support body is fixed to the bottom of the second support part, and the second support body abuts against the side wall of the crown beam retaining wall. The end of the second support part in the first support body is directly inserted into the inner side of the extension part and is fixedly connected to the first support body.

[0007] Furthermore, a first embedded part and a second embedded part are fixed on the crown beam retaining wall, the first embedded part is provided with a first embedded bolt, and the second embedded part is provided with a second embedded bolt. The first embedded part is fixedly connected to the first support body by the first embedded bolt, and the second embedded part is fixedly connected to the second support body by the second embedded bolt.

[0008] Furthermore, the first support body is provided with a plurality of first reinforcing plates, each of which is provided with a first mounting hole that cooperates with the first embedded bolt, and the second support body is provided with a plurality of second reinforcing plates, each of which is provided with a second mounting hole that cooperates with the second embedded bolt.

[0009] Furthermore, symmetrical wing plates are fixed on both sides of the second support portion. By arranging symmetrical wing plates on both sides of the second support portion, the second support portion is widened, the contact area between the second support portion and the side wall of the crown beam retaining wall is increased, and the horizontal bearing capacity of the first support body is improved.

[0010] Furthermore, the extension part is provided with a plurality of third mounting holes, the second support part is provided with a plurality of fourth mounting holes matched with the third mounting holes, and bolts are passed through the third mounting holes and the fourth mounting holes to achieve the fixing of the second support part and the extension part. The third mounting hole is matched with the fourth mounting hole so that the extension part is stably fixed to the end of the second support part of the first support body.

[0011] Furthermore, at least one third reinforcing plate is provided in the first support body, and the third reinforcing plate is perpendicular to the first reinforcing plate, so as to increase the structural strength of the first support body and improve the supporting strength of the first support body.

[0012] Furthermore, at least one fourth reinforcing plate is provided in the second support body, and the fourth reinforcing plate is perpendicular to the second reinforcing plate, so as to increase the structural strength of the second support body and improve the supporting strength of the second support body.

[0013] Through the above technical scheme, the beneficial effects of the utility model are as follows: the extension portion fixed at the end of the second support portion in the first support body of the utility model lengthens the support length of the first support body, and only the length of the extension portion needs to be changed to ensure that the track support beam of the special-shaped expansion section matches the track support beam at the vertical standard section to form a horizontal line. Compared with the separately designed corbel support, it can be more convenient to construct and improve on-site work efficiency. The first support portion of the first support body and the second support body fixed at the lower end of the first support body are fixed on the side wall of the crown beam retaining wall, and at the same time bear the gravity of the track support beam, with large supporting capacity and strong versatility.
