BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of the present invention;

[0015] Figure 2 yes Figure 1 A partial enlarged view of point A in the middle. DETAILED DESCRIPTION

[0016] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 to Figure 2 As shown, a large-span truss brick unloading and loading equipment includes a truss 10, wherein the truss 10 includes a crossbeam 1001 and two first columns 1002 respectively arranged at both ends of the crossbeam 1001, and the truss 10 is provided with a trolley 1 that reciprocates on the crossbeam 1001.

[0018] A ground rail 2 is arranged between the two first columns 1002, the top of the ground rail 2 is against the cross beam 1001, and the ground rail 2 includes a second column 201, a support seat 202 is arranged on the top of the second column 201, and a running wheel 203 is arranged on the bottom. The support seat 202 supports the cross beam 1001, and there are two second columns 201, which are symmetrically arranged below the support seat 202 and fixedly connected to the support seat 202. The running wheel 203 makes the ground rail 2 easy to move, and is convenient for disassembly, installation and relocation.

[0019] The bottom of the trolley 1 is fixedly connected with a fixing frame 9 , and the fixing frame 9 includes a rectangular plate 901 arranged below the crossbeam 1001 , and the rectangular plate 901 is fixedly connected to the crossbeam 1001 through four connecting rods 902 .

[0020] The fixed frame 9 is provided with a lifting electric hoist 8, and a lifting plate 7 connected to the lifting electric hoist 8 is provided below the fixed frame 9. Four guide posts 6 are fixedly installed on the lifting plate 7, and each guide post 6 is inserted in a guide sleeve assembly 5. The four guide posts 6 are respectively inserted at the four corners of the rectangular plate 901. There are four guide sleeve assemblies 5 in total. The guide sleeve assembly 5 includes a first guide sleeve 501, a connecting pipe 502, and a second guide sleeve 503 which are sequentially sleeved on the guide posts 6 from top to bottom. The two ends of the connecting pipe 502 are respectively fixedly connected to the first guide sleeve 501 and the second guide sleeve 503, and the first guide sleeve 501 is fixedly connected to the rectangular plate 901. The guide sleeve assembly 5 ensures that the position of the lifting plate 7 will not be offset when it rises or falls along the axial direction of the guide posts 6.

[0021] The bottom of the lifting and rotating plate 7 is fixedly mounted with a slewing support 4, and a brick clamping mechanism 3 for clamping bricks is arranged below the slewing support 4. The brick clamping mechanism 3 is connected to the slewing support 4. The slewing support 4 is widely used in the prior art. The slewing support 4 drives the brick clamping mechanism 3 to rotate, so that the angle is easy to adjust when clamping or unloading bricks. When the lifting and rotating plate 7 rises or falls, it drives the slewing support 4 and the brick clamping mechanism 3 to rise or fall.

[0022] The brick clamping mechanism 3 includes a U-shaped arm 301 with an opening facing downward and two clamping components symmetrically arranged at both ends of the U-shaped arm 301, the clamping component includes a clamping leg 302, a web 303, a bottom plate 304, a first spring 305, a first rubber plate 306 and a second rubber plate 307 arranged below the U-shaped arm 301, the middle part of the clamping leg 302 is hinged to the end of the U-shaped arm 301 through a first hinge shaft 308, the lower part of the clamping leg 302 is hinged to the web 303 through a second hinge shaft 3018, the bottom plate 304 is fixedly connected to the web 303, the first rubber plate 306 is attached to the upper part of the side wall of the bottom plate 304 away from the web 303, and the second rubber plate 307 is attached to the lower part of the side wall of the bottom plate 304 away from the web 303. The U-shaped arm 301 has one end fixedly connected to the base plate 304, and the other end fixedly connected to the clamping leg 302. A clamping cylinder 3013, a gear synchronizer 3014 and clamping assemblies symmetrically arranged at both ends of the clamping cylinder 3013 are arranged above the U-shaped arm 301. The clamping assembly includes a gear 3015, a first connecting rod 3016 and a second connecting rod 3017. One end of the first connecting rod 3016 is fixedly connected to the center of the gear 3015, and the other end is hinged to one end of the second connecting rod 3017. The other end of the second connecting rod 3017 is hinged to the upper part of the clamping leg 302. The two gears 3015 in the two clamping assemblies are meshed, and the two clamping legs 302 in the two clamping assemblies are fixedly connected to the telescopic rod and cylinder body of the clamping cylinder 3013 respectively.

[0023] When the brick clamping mechanism 3 clamps bricks, the telescopic rod of the clamping oil cylinder 3013 extends to push the upper parts of the two clamping legs 302 to move outwards. At this time, the lower parts of the two clamping legs 302 approach each other, thereby clamping the bricks. The bottom of the brick pile is clamped between the two bottom plates 304, and the first rubber plate 306 and the second rubber plate 307 are attached to the bricks at the bottom of the brick pile. The first rubber plate 306 and the second rubber plate 307 play a role of anti-skid and buffering, so that bricks of various strengths can be clamped; when clamping bricks, the first spring 305 tightens the bottom plate 304, giving the bottom plate 304 a vertical upward force, so that the bottom plate 304 drags the bottom of the brick pile. The gear synchronizer 3014, the gear 3015, the first connecting rod 3016 and the second connecting rod 3017 ensure that the two clamping legs 302 move synchronously. When unloading bricks, the telescopic rod of the clamping oil cylinder 3013 retracts, so that the lower parts of the clamping legs 302 are separated from each other, and then the bricks are unloaded.

[0024] The bottom plate 304 and the web plate 303 are arranged vertically.

[0025] The U-shaped arm 301 is provided with a brick pressing assembly, which includes a brick pressing plate 309, four fixed columns 3010, and four second springs 3011 respectively sleeved on the four fixed columns 3010. The brick pressing plate 309 is arranged below the fixed columns 3010. The upper part of the fixed columns 3010 is fixedly connected to the U-shaped arm 301. The middle part of the fixed column 3010 is fixedly installed with a limit ring 3012. The upper part of the second spring 3011 abuts against the limit ring 3012, and the lower part is fixedly connected to the brick pressing plate 309. After the brick clamping mechanism 3 clamps the bricks, the top layer of the bricks abuts against the brick pressing plate 309. Under the action of the second spring 3011, the brick pressing plate 309 presses on the top layer of the brick pile, which is more stable when moving bricks, reduces the shaking amplitude, and is not easy to drop bricks.

[0026] The above embodiments are based on the technical solutions of the present invention, and provide detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to the above embodiments.
