[0002] Large span refers to the various structural forms of building that cross 30 meters horizontally, and large-span structures are often used in large-span factory buildings, aircraft assembly workshops and large warehouses in industrial buildings.
[0003] Beamless arch is an arch-shaped groove plate formed by galvanized steel plate through continuous rolling forming machine, and the thickness of the groove plate is 0.6mm-1.5mm. The groove plates are connected and assembled into a whole by an edge sealing machine, and finally a secondary machine is used to form a whole by engaging the groove plates.
[0004] During the lifting of the beamless arch, a crane or other equipment is usually used to lift the rope tied to the arch plate of the beamless arch. During lifting, the rope may slip or be tied too close, causing deformation and instability of the beamless arch.
[0005] Therefore, a large-span beamless arch hoisting fixture is needed to solve the above problems. INVENTION CONTENTS
[0006] The utility model aims to provide a large-span beamless arch hoisting fixture to solve the problem of instability caused by deformation and instability of the beamless arch during lifting.
[0007] To solve the above technical problems, the utility model adopts the following technical scheme: a large-span beamless arch hoisting fixture, comprising a left clamp plate, a right clamp plate, a control bolt, a rotating hinge, a steel rope pulley and a non-slip rubber pad.
[0008] The steel rope pulley is connected to the lifting device by a steel rope.
[0009] The left clamp plate is hingedly connected to the left side of the steel rope pulley.
[0010] The right clamp plate is hingedly connected to the right side of the steel rope pulley.
[0011] The control bolt is arranged in the middle of the right clamp plate, and the left end is fixed by a locking nut after passing through the left clamp plate.
[0012] The non-slip rubber pad comprises a left non-slip rubber pad and a right non-slip rubber pad. The left non-slip rubber pad is arranged on the inner wall of the left clamp plate, and the right non-slip rubber pad is arranged on the inner wall of the right clamp plate. The left non-slip rubber pad and the right non-slip rubber pad form an inclined gap in the middle for locking the arch plate joint of the beamless arch.
[0013] As a further technical solution of the above solution, a limit block is further provided on the control bolt, and the limit block is vertically arranged to press against the inner wall of the left clamping plate.
[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects: the utility model provides a left clamping plate and a right clamping plate, and respectively provides anti-skid rubber pads on the inner walls of the left clamping plate and the right clamping plate, and the left anti-skid rubber pad and the right anti-skid rubber pad fit the locking mouth of the beamless arch plate for clamping, thereby improving the stability of clamping while avoiding damage to the locking mouth of the beamless arch plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 This is a schematic diagram of the use state of the utility model.
[0017] The meanings of the numbers in the figure are: left clamping plate - 1; right clamping plate - 2; control bolt - 3; rotary hinge - 4; steel rope pulley - 5; left anti-slip rubber pad - 61; right anti-slip rubber pad - 62; locking nut - 7; limit block - 8. DETAILED DESCRIPTION
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.
[0019] like Figure 1 and Figure 2 As shown, a large-span beamless arch lifting fixture includes a left clamping plate 1, a right clamping plate 2, a control bolt 3, a rotating hinge 4, a steel rope pulley 5 and an anti-slip rubber pad;
[0020] a rope pulley 5 connected to the sling via a steel rope;
[0021] The left clamping plate 1 has its upper end hinged to the left side of the steel rope pulley 5;
[0022] The right splint 2 has its upper end hinged to the right side of the rope pulley 5;
[0023] The right end of the control bolt 3 is set in the middle of the right clamping plate 2, and the left end passes through the left clamping plate 1 and is fixed with a lock nut 7;
[0024] The anti-slip rubber pad includes a left anti-slip rubber pad 61 and a right anti-slip rubber pad 62; the left anti-slip rubber pad 61 is arranged on the inner wall of the left clamping plate 1; the right anti-slip rubber pad 62 is arranged on the inner wall of the right clamping plate 2; an inclined gap is formed between the left anti-slip rubber pad 61 and the right anti-slip rubber pad 62 for locking the beamless arch plate lock.
[0025] When using this device, first assemble the beamless arch to be hoisted. The assembly point of adjacent beamless arches is the inclined beamless arch arch plate lock. Use the left clamping plate 1 close to the left side of the beamless arch arch plate lock, and the right clamping plate 2 close to the right side of the beamless arch arch plate lock; the left anti-slip rubber pad 61 and the right anti-slip rubber pad 62 are respectively pressed against the beamless arch arch plate lock, and match the inclined setting of the beamless arch arch plate lock, thereby improving the clamping effect; while adjusting, control the bolt 3 to pass through the left clamping plate 1 at the same time, and use the locking nut to fix it, completing the installation of the clamp, which is convenient for subsequent hoisting operations.
