With this structural arrangement, a steel beam clamping area is formed between the movable clamping portion 200 and the fixed clamping portion 100. The movable grip 200 is provided at its end with a locking member 400. The steel beam is placed in the steel beam clamping area, clamped by the movable clamping portion 200 and the fixed clamping portion 100, and locked in the steel beam clamping area by the locking member 400. From this, this joist device's centre gripping girder steel stability and security are higher, can effectively avoid the girder steel to drop the incident that causes.
For example, the locking piece comprises a locking baffle, one end of the locking baffle is connected with the outer end part of the movable clamping part, and the other end of the locking baffle is a free end and extends to the upper part of the inner side of the steel beam clamping area. The outside of U shaped steel roof beam can be arranged in to the free end of locking baffle card to lock U shaped steel roof beam in girder steel clamping area. Alternatively, the locking piece can also be a locking rod or the like.
In an embodiment of the present invention, the fixing clip part 100 is formed with a first clip surface 101. The movable clamping portion 200 is formed with a second clamping surface 201. The first clamping surface 101 and the second clamping surface 201 can together form a U-shaped clamping surface. The inner side of the U-shaped clamping surface is a steel beam clamping area.
For example, as shown in fig. 2, in this embodiment, the first clamping surface 101 includes a first section and a second section. For example, the first section is horizontally disposed. The first section and the second section may be arranged at an obtuse angle or a right angle. The second section and the second clamping surface 201 are respectively arranged at two ends of the first section. The first section, the second section and the second clamping surface 201 together form a U-shaped clamping surface. Through the structure, the joist device is more suitable for clamping the U-shaped steel beam 700. When clamping the U-shaped steel beam 700, two outer side surfaces of the U-shaped steel beam 700 can be attached to the second section of the first clamping surface 101 and the second clamping surface 201. This can improve the clamping stability of the U-shaped steel beam 700.
In an embodiment of the present invention, a first engaging groove 102 is formed on an outer end portion of the first clamping surface 101. A second clamping groove 202 is formed at the outer end of the second clamping surface 201. The first engaging groove 102 and the second engaging groove 202 are respectively adapted to two side edges of the U-shaped steel beam 700, so that the two side edges of the U-shaped steel beam 700 can be respectively engaged with the first engaging groove 102 and the second engaging groove 202.
Further, in an embodiment of the present invention, the locking member 400 includes a safety catch 401. One end of the safety latch hook 401 is connected with the outer end of the movable clamping part 200, and the other end of the safety latch hook 401 extends to the inner side of the steel beam clamping area. And the safety lock hook 401 is located at the outer side of the second lock slot 202, so that one side edge of the U-shaped steel beam 700 can be clamped and locked between the first lock slot 102 and the safety lock hook 401.
Specifically, as shown in fig. 2, when the U-shaped steel beam 700 is clamped, two outer side surfaces of the U-shaped steel beam 700 are respectively attached to the first clamping surface 101 and the second clamping surface 201. One side edge of the U-shaped steel beam 700 is clamped in the first clamping groove 102, and the other side edge of the U-shaped steel beam 700 is clamped in the second clamping groove 202. Meanwhile, a safety latch hook 401 is provided at an upper side of the second card slot 202. One end of the safety catch 401 extends to the inside of the steel beam clamping area. When the U-shaped steel beam 700 is clamped between the movable clamping portion 200 and the fixed clamping portion 100, the safety lock hook 401 can lock one side edge of the U-shaped steel beam 700 between the safety lock hook 401 and the second locking groove 202. This allows the U-shaped steel beam 700 to be clamped and locked in the joist device in a stable manner.
For another example, in order to further improve the clamping and locking stability of the joist device, a plurality of safety hooks 401 may be provided at intervals on the movable clamping portion 200. As shown in fig. 1, in this embodiment, two safety catch hooks 401 are provided at intervals on the movable clip part 200.

The first engaging grooves 102 are arranged in a descending stair manner in the direction from the outer side to the inner side of the steel beam clamping area. The number of second card slots 202 is equal to the number of first card slots 102. The arrangement positions of the second card slots 202 correspond one-to-one to the arrangement positions of the first card slots 102.
For example, as shown in fig. 2, an opening of a steel beam clamping area formed between the movable clamping portion 200 and the fixed clamping portion 100 faces upward. A plurality of first card slots 102 are disposed on the second section of the first clamping surface 101, and a plurality of second card slots 202 are correspondingly disposed on the second clamping surface 201. In a direction from the opening of the steel beam clamping area to the inside of the steel beam clamping area, i.e., in a direction from top to bottom as shown in fig. 2, the first slots 102 are arranged in a descending stair manner, and correspondingly, the second slots 202 are arranged in a descending stair manner. That is, the distance between the first card slot 102 and the second card slot 202 of the same stage decreases gradually along the direction from top to bottom.
Through the structure, the U-shaped steel beams 700 with different sizes can be clamped and clamped between the movable clamping part 200 and the fixed clamping part 100, and the application range and the use flexibility of the joist device are further improved.

For example, as shown in fig. 1 and 2, one end of the boom connecting part 600 is fixedly connected to the fixed clamping part 100. For example, the arm connecting portion 600 is welded to the fixed clamp portion 100. The boom connecting portion 600 is provided with a first through hole and a second through hole. The end part of the arm support is provided with a first adaptive through hole and a second adaptive through hole. The first adaptive through hole is matched with the first through hole, and the second adaptive through hole is matched with the second through hole. When the joist device is installed, pin shafts are respectively arranged between the first penetrating hole and the first adaptive penetrating hole in a penetrating way and between the second penetrating hole and the second adaptive penetrating hole in a penetrating way. So that the joist device is fixed to the end part of the cantilever crane for roadway support operation.

One end of the clamping cylinder is rotatably connected with the arm support connecting part 600, and the other end of the clamping cylinder is rotatably connected with the movable clamping part 200.
For example, as shown in fig. 2, the movable clamp portion 200 includes a clamping section and a driving rotation section. The clamping section is used for clamping the U-shaped steel beam 700 in cooperation with the fixing and clamping portion 100. The driving rotation section is connected with the clamping oil cylinder, and the clamping oil cylinder drives the driving rotation section to rotate so as to drive the clamping section to rotate and adjust the size of the steel beam clamping area.
The end part of one end of the clamping section is provided with a safety lock hook 401, the other end of the clamping section is connected with one end of the driving rotating section, the other end of the driving rotating section is hinged with one end of the clamping oil cylinder, and the other end of the clamping oil cylinder is hinged with the arm support connecting part 600. The clamping section and the driving rotation section are arranged at an angle.
When a piston rod of the clamping oil cylinder extends, the clamping oil cylinder drives the rotating section to drive the clamping section to rotate anticlockwise so as to increase the size of an opening of a steel beam clamping area. When the piston rod of the clamping oil cylinder contracts, the clamping oil cylinder drives the driving rotating section to drive the clamping section to rotate clockwise, so that the size of an opening of a steel beam clamping area is reduced.
