Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, specifically relating to a double-layer suspended crane. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. Because their ends rest on tall concrete pillars or metal supports, they resemble bridges. The bridge frame of a bridge crane runs longitudinally along rails laid on elevated structures on both sides, making full use of the space beneath the bridge frame for material handling without being obstructed by ground equipment. It is the most widely used and numerous type of lifting machinery.

[0003] However, when dealing with lifting large and irregularly shaped objects, it is not possible to quickly lift them using a single hoist and overhead crane. Furthermore, when using a single hoist to lift irregularly shaped objects, the design for securing the cargo requires a lengthy process. The improved design can add multiple sets of crossbeams, with multiple hoists mounted on them, allowing for faster securing of the cargo when lifting irregularly shaped objects. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a double-layer suspended crane.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a double-layer suspended crane, including two main end beams arranged front and rear, with the left and right ends of the two main end beams respectively connected to the main beams, characterized in that: multiple crossbeams are slidably arranged between the two main beams, and multiple electric hoists are slidably arranged on the surface of each crossbeam, with the bottom of each electric hoist connected to a ground operating handle via an electric wire, and auxiliary end beams are arranged at the bottom of both ends of each crossbeam, with guide wheels interacting with the main beams at the four corners of the bottom of each auxiliary end beam, and a motor providing power to one of the guide wheels is arranged on its side, and anti-collision sleeves and impact sleeves are respectively arranged on the side of the two auxiliary end beams of the same main beam facing each other and on the side of the two electric hoists of the same crossbeam facing each other.

[0006] Preferably, a C-shaped steel sliding guide system is provided on one side of each of the main beams on both sides, and a drag chain power supply system is provided on the top of the electric hoist.

[0007] Preferably, the anti-collision sleeve is disposed on both sides of one of the electric hoists and on both sides of the auxiliary end beam. An insertable colloid is inserted into the inside of the anti-collision sleeve, and an insertable cavity is formed between the insertable colloid and the inner cavity of the anti-collision sleeve. A first insertable rod is disposed on the top of the anti-collision sleeve, and two first positioning bolts are threadedly connected to the first insertable rod.

[0008] Preferably, the surface of the anti-collision sleeve is provided with a plurality of lateral pressure-permeable holes, and the bottom of the anti-collision sleeve is provided with a first bottom pressure-permeable hole around the outer ring of the first plug rod.

[0009] Preferably, the impact sleeve is provided on the side where the electric hoist is equipped with the anti-collision sleeve and on the side where the auxiliary end beam is equipped with the anti-collision sleeve. The impact sleeve has a cavity for inserting the colloid inside, and the outer ring of the cavity has multiple lateral pressure grooves corresponding to the inner wall of the impact sleeve. The bottom of the impact sleeve is provided with a second insertion rod, and the surface of the second insertion rod is threaded with two second positioning bolts. The bottom of the impact sleeve has a second bottom pressure hole around the outer ring of the second insertion rod.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting multiple sets of crossbeams between the two main beams, and installing multiple electric hoists on the crossbeams as needed, it is possible to lift irregularly shaped objects more stably and quickly, and the initial winding of the lifting rope is simpler for irregular objects.

[0012] 2. Two adjacent auxiliary end beams sliding on the main beam are close to each other on one side. One is equipped with a collision protection sleeve and the other with an impact sleeve. When the proximity switch fails, it can play a better role in preventing collisions. Compared with the traditional rubber ring for anti-collision, it can reduce the impact pressure by the ring-shaped collision protection sleeve during an impact. It also has an insertable rubber body inside, which inserts into the impact sleeve to increase the impact reduction effect. In conjunction with the lateral pressure-permeable holes on the surface, the first bottom pressure-permeable hole and the second bottom pressure-permeable hole, the air pressure generated by internal compression can be discharged through these holes and grooves when an impact occurs.

[0018] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] Example: A double-layer suspended crane, such as Figures 1-4 As shown, the system includes two main end beams 1 arranged front and rear, with main beams 2 connected to the left and right ends of the two main end beams 1 respectively. A C-shaped steel sliding guide system 3 is provided on one side of each main beam 2. A drag chain power supply system 7 is provided on the top of the electric hoist 4. Multiple crossbeams 6 are slidably arranged between the two main beams 2. Multiple electric hoists 4 are slidably arranged on the surface of each crossbeam 6. The bottom of the electric hoist 4 is connected to a ground operating handle 41 via a wire. Auxiliary end beams 5 are provided at the bottom of both ends of the crossbeam 6. Guide wheels 51 that interact with the main beam 2 are provided at the four corners of the bottom of the auxiliary end beams 5. A motor 52 that provides power to one of the guide wheels 51 is provided on its side. Anti-collision sleeves 9 and impact sleeves 11 are provided on the side of the two auxiliary end beams 5 facing each other and the side of the two electric hoists 4 facing each other on the crossbeam 6 respectively.

[0020] The anti-collision sleeve 9 is installed on both sides of one of the electric hoists 4 and both sides of the auxiliary end beam 5. The anti-collision sleeve 9 has an insertable colloid 91 inserted inside, and an insertable cavity 92 is formed between the insertable colloid 91 and the inner cavity of the anti-collision sleeve 9. The top of the anti-collision sleeve 9 is provided with a first insertable rod 94, and two first positioning bolts 95 are threaded on the first insertable rod 94. The surface of the anti-collision sleeve 9 is provided with multiple lateral pressure holes 93, and the bottom of the anti-collision sleeve 9 is provided with a first bottom pressure hole 96 around the outer ring of the first insertable rod 94.

[0021] Impact sleeve 11 is provided on the side of electric hoist 4 where anti-collision sleeve 9 is provided and on the side of auxiliary end beam 5 where anti-collision sleeve 9 is provided. The impact sleeve 11 has a cavity 111 for inserting colloid 91 inside. The outer ring of the cavity 111 has multiple lateral pressure grooves 112 corresponding to the inner wall of the impact sleeve 11. The bottom of the impact sleeve 11 is provided with a second insertion rod 113. The surface of the second insertion rod 113 is threaded with two second positioning bolts 114. The bottom of the impact sleeve 11 has a second bottom pressure hole 115 around the outer ring of the second insertion rod 113.

[0022] The principle of this invention is as follows: When lifting irregularly shaped objects, it is usually necessary to thoroughly tie the bottom of the object with ropes before using two electric hoists 4, and then find the balance point of the object on the hooks of the two electric hoists 4 before lifting to prevent the object from tipping over due to the center of gravity after lifting. However, in this device, by setting up a crossbeam 6 and multiple electric hoists 4, when lifting irregularly shaped objects, the ropes only need to be tied around the object once. Then, by attaching hooks to the four loops of the object, the object can be lifted more quickly, and the preparation is also faster.

[0023] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
