Description

Adjustable Truss Assembly Support Frame

technical field

The utility model belongs to the technical field of escalators, and in particular relates to an adjustable truss assembling support frame used for assembling an escalator.

Background technique

The truss is an important part of supporting the entire escalator. Whether the installation of the truss meets the specifications will have a great impact on the safety and stability of the escalator in the future. Therefore, when the escalator truss is installed, it is necessary to have a support frame to withstand the bottom of the truss to improve the installation of the truss. level and vertical accuracy. At present, two rectangular tubes are placed under the sectional escalator during final assembly. Because the segments of each escalator are inconsistent, the height of the shelf needs to be changed. Each time, the rectangular tube needs to be re-measured and made, and because the two rectangular tubes are not mutually connection, so the security is not reliable.

Contents of the invention

The technical problem to be solved by the utility model is to provide an assembly support frame for supporting when the escalator truss is installed, the height of the support frame can be adjusted according to the position and height of the escalator truss.

In order to solve the above technical problems, the utility model is realized through the following technical solutions: an adjustable truss assembly support frame, the support frame is a left-right symmetrical structure, and the support frame includes a base frame, an adjustment device and a support device , the base frame is a T-shaped structure formed by vertically connecting the bottom plate and the support pipe, and the two support pipes are connected by a beam; the adjustment device is composed of a connecting flange, a guide, an internal screw and an adjustment The connecting flange is fixedly connected to the upper end of the support pipe by threads, the guide is fixedly installed on the upper end of the connecting flange, the inner screw guide is threaded, the adjusting handle is set on the upper end of the inner screw and can be used for The rotation controls the internal screw to move up and down relative to the guide; the support device is fixedly connected to the upper end of the internal screw, and the support device is provided with a support plate for supporting the truss.

Preferably, reinforcing plates are provided on both sides of the support tube, one end of the reinforcing plate is fixedly connected to the bottom plate, and the other end is fixedly connected to the support tube, and the inclination angle of the reinforcing plate is 45°.

Preferably, the support plate and the support device are connected flexibly by bolts, and the support plate can rotate around the bolts.

Preferably, the support plate can be disassembled and separated from the support device.

Compared with the prior art, the utility model has the advantages that the support frame can be adjusted in height according to the position of the support truss, which improves the safety of the truss installation and is suitable for any type of truss support.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is the front view of the utility model.

Fig. 2 is a left view of the utility model.

Fig. 3 is an enlarged view of the adjusting device of the present invention.

In the figure: 11, bottom plate; 12, support pipe; 13, reinforcing plate; 14, beam; 21, connecting flange; 22, guide piece; 23, inner screw; 24, adjustment handle; 3, support device; 31, support plate; 4, bolts.

Detailed ways:

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:

An adjustable truss assembly support frame as shown in Figures 1 to 3, the support frame is a left and right symmetrical structure, the support frame includes a base frame, an adjustment device and a support device 3, and the base frame is composed of The bottom plate 11 and the support pipe 12 are vertically connected to form a T-shaped structure, and the two support pipes 12 are connected by a crossbeam 14; The connecting flange 21 is fixedly connected to the upper end of the bracket pipe 12 by screw thread, the guide piece 22 is fixedly installed on the upper end of the connecting flange 21, the inner screw rod 23 guide piece 22 is threadedly connected, and the adjusting handle 24 It is arranged on the upper end of the inner screw 23 and can be used to rotate and control the inner screw 23 to move up and down relative to the guide 22; the support device 3 is fixedly connected to the upper end of the inner screw 23, and the support device 3 is provided with a support for supporting the truss. Support plate 31. When supporting the truss that needs to be installed, the entire support frame can be adjusted by adjusting the handle 24 to stably support the truss.

In order to increase the overall strength of the base frame, reinforcing plates 13 are also provided on both sides of the support tube 12, one end of the reinforcing plate 13 is fixedly connected to the bottom plate 11, and the other end is fixedly connected to the support tube 12, the reinforcing plate 13 The inclination angle is 45°.

The support plate 3 and the support device 3 are flexibly connected by bolts 4, the support plate 3 can rotate around the bolt 4, and the angle of the support plate 3 can be automatically changed according to the angle of the truss at different positions.

Since the bolts 4 at the support plate 3 need to withstand a large shearing force, the support plate 3 can be disassembled and separated from the support device 3 so as to be replaced after the support plate 3 or the bolts 4 are damaged.

It should be emphasized that: the above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any simple modification, equivalent change and Modifications still belong to the scope of the technical solution of the utility model.
