As the preference in above-mentioned scheme, side guard plate and end guard plate are formed by the steel sheet welding, the side guard plate includes two horizontal steel sheets and is used for connecting the vertical steel sheet of two horizontal steel sheets, end guard plate adopts the box-packed structure that forms by bottom plate, roof and front and back curb plate welding, and the interval is provided with the polylith floor that is used for connecting two front and back curb plates in the box-packed structure.

Further preferably, the rib plates at the bottom of the T-shaped lifting beam are arranged at left and right intervals, and the rib plates at the left and right ends of the T-shaped lifting beam are arranged at up and down intervals.

Further preferably, the bottom guard plate adopts a split structure and is formed by splicing two parts which are bilaterally symmetrical.

The utility model has the beneficial effects that: the edge angle at the lower end of the T-shaped handle is protected by the bottom guard plate, and the edge angles at the left side and the right side of the upper end of the T-shaped handle are protected by the two side guard plates, so that the edge angle of the T-shaped handle can be effectively protected; the side guard plates can cover the left end and the right end of the upper end of the T-shaped lifting beam, and then the bottom guard plates cannot fall under the double actions of the pulling force of the steel wire rope and the gravity of the T-shaped lifting beam, so that the condition of high-altitude falling objects in the lifting process can be avoided; rubber backing plates which are used for being in contact with the T-shaped lifting beam are arranged on the inner sides of the side guard plate and the bottom guard plate, so that the edges and corners of the T-shaped lifting beam can be better protected; lifting lugs are arranged on the side guard plates and the bottom guard plates, so that the installation is convenient.

Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in fig. 1-3, an edge guard board for lifting a T-shaped lifting beam mainly comprises a bottom guard board 1 and a side guard board 2, wherein the inner sides of the bottom guard board 1 and the side guard board 2 are used for protecting the edge of the T-shaped lifting beam, and the outer sides are used for being in contact with a steel wire rope of lifting equipment. The upper inner end of the bottom guard plate 1 is U-shaped and is just clamped at the bottom of the T-shaped lifting beam from below, and the lower outer end of the bottom guard plate 1 is arc-shaped for facilitating steel wire rope hoisting. The side guard plates 2 are fang -type and are arranged left and right oppositely, and the two side guard plates 2 just cover the left end and the right end of the upper end of the T-shaped lifting beam from the left end and the right end respectively.

In order to prevent the steel wire rope from separating from the guard plate, arc-shaped notch 5 for limiting the steel wire rope is arranged on the outer side of the bottom guard plate 1 and the outer side of the side guard plate, namely, on the side, in contact with the steel wire rope, of the bottom guard plate 1 and the side guard plate 2. Because the bottom guard plate 1 and the side guard plate 2 need bear the gravity of the T-shaped lifting beam and the tensile force of the steel wire rope, the bottom guard plate 1 and the side guard plate 2 are made of hard materials, rubber backing plates 3 are arranged on the inner sides of the bottom guard plate 1 and the side guard plate 2, namely on the sides of the bottom guard plate 1 and the side guard plate 2, which are in contact with the T-shaped lifting beam, and other soft materials can be adopted for the rubber backing plates. In order to facilitate clamping the side guard plates 2 and the bottom guard plates 1 on the T-shaped lifting beam, lifting lugs 4 are arranged on the top surfaces of the side guard plates 2 and the middle parts of the top surfaces of the bottom guard plates 1 at the left end and the right end of the T-shaped lifting beam.

The side guard plate 2 and the bottom guard plate 1 are formed by welding steel plates, wherein the side guard plate 2 comprises two horizontal steel plates 2a and a vertical steel plate 2b for connecting the two horizontal steel plates, and the arc-shaped notch 5 is arranged on the outer side of the vertical steel plate, namely, one side of the vertical steel plate deviating from the horizontal steel plate. The bottom guard plate 1 has a box-packed structure formed by welding a bottom plate 1a, a top plate 1b and front and rear side plates 1c, and an arc-shaped groove 5 is provided below the bottom plate 1 a. In order to increase the strength of the bottom guard plate, a plurality of rib plates 1d for connecting the two front and rear side plates 1c are arranged in the box structure at intervals. Preferably, the rib plates 1d positioned at the bottom of the T-shaped lifting beam are arranged at left and right intervals, and the rib plates 1d positioned at the left and right ends of the T-shaped lifting beam are arranged at up and down intervals.

Because the whole bottom guard plate is heavier, the bottom guard plate 1 adopts a split type structure, namely the bottom guard plate 1 is formed by splicing two parts which are bilaterally symmetrical, thereby facilitating the installation of the bottom guard plate 1.

Before hoisting, two side guard plates are covered at the left end and the right end of the upper end of the T-shaped lifting beam correspondingly, then the bottom guard plates are placed at the bottom of the T-shaped lifting beam, and then the steel wire ropes bypass the side guard plates, the bottom guard plates and the other side guard plates in sequence.
