DETAILED DESCRIPTION

[0024] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0025] Referring to Figures 1-6 The utility model provides a technical scheme of tower crane hopper with protection structure:

[0026] Referring to Figure 1 And Figure 2 A tower crane hopper with a protection structure, comprising a hopper 1, the top end of the hopper 1 is provided with a top frame body 11, the top corner of the top frame body 11 is provided with an angle block 12, two adjacent angle blocks 12 are provided with a fixed shaft 2, the fixed shaft 2 is rotatably connected with a sleeve 21, both ends of the sleeve 21 are connected with a swivel block 22 through a torsion spring 23, the arc side of the swivel block 22 is fixedly connected with a side clamping block 25, the side of the angle block 12 is provided with a positioning block 26 close to the swivel block 22, the sleeve 21 is fixedly connected with a steel mesh plate 24, the top surface of the steel mesh plate 24 is fixedly connected with a top block 3 away from the sleeve 21, the top surface of the top block 3 is provided with a hook groove 31, and the top block 3 is clamped with a clamping ring 32 at the hook groove 31.

[0027] Need to be supplemented is that when the clamping ring 32 is clamped with the hook groove 31 on the top block 3, the side clamping block 25 is in close contact with the positioning block 26, and at this time, the torsion spring 23 is in a state of storing torsional potential energy.

[0028] Referring to Figure 1 In an optional embodiment, the angle block 12 is provided with four, the fixed shaft 2 is provided with four, the steel mesh plate 24 is provided with four, and the clamping ring 32 is provided with one, wherein it needs to be supplemented that the top end of the hopper 1 is quadrangular at this time, and the top frame body 11 is correspondingly quadrangular.

[0029] Need to be supplemented is that the swivel block 22 is attached to the side of the angle block 12 and rotates with the sleeve 21, the torsion spring 23 is sleeved on the fixed shaft 2, and the torsion spring 23 is not in contact with the fixed shaft 2.

[0030] Referring to Figure 5As shown, in an optional embodiment, the top block 3 is configured as a cuboid, and the hook groove 31 is opened at the end of the top block 3 away from the sleeve 21. It should be noted that rotating the wire mesh plate 24 can cause the retaining ring 32 to disengage from the hook groove 31, thereby breaking the engagement between the retaining ring 32 and the hook groove 31. Furthermore, when the retaining ring 32 is engaged with the hook groove 31 on the four top blocks 3, the four wire mesh plates 24 move closer together to cover the top opening of the hopper 1. When the retaining ring 32 is engaged with the hook groove 31 on the four top blocks 3, the angle between the four wire mesh plates 24 and the horizontal plane is an acute angle. Through this arrangement, after the four wire mesh plates 24 are fixed, the four wire mesh plates 24 also form a protruding space at the top of the hopper 1, thereby allowing the hopper 1 to be filled with more material, thus improving the handling efficiency of the hopper 1.

[0031] Reference Figure 1 and Figure 6 As shown, lifting lugs 13 are fixedly connected to the center of the two symmetrical sides of the top frame 11 for hoisting the device. It should be noted that the lifting lugs 13 are square frames. During use, the lifting lugs 13 can be hooked by the hooks on the tower cranes in the prior art, thereby lifting, moving and hoisting the hopper 1.

[0032] The working principle of this device is explained through its usage process: When using this device, first fill the hopper 1 with the material to be hoisted. After the material is full, move the wire mesh plate 24 towards the top center of the hopper 1. At this time, the sleeve 21 and the rotating block 22 rotate on the fixed shaft 2 until the side locking block 25 and the positioning block 26 contact. Then, take out the retaining ring 32 and slide it down along the top surface of the top block 3. At this time, because the side locking block 25 and the positioning block 26 are in contact, the rotation of the rotating block 22 is restricted. The sleeve 21 continues to rotate on the fixed shaft 2. The torsion spring 23 will accumulate torsional potential energy, and the downward sliding retaining ring 32 will be locked into the hook groove 31. Under the action of the torsional potential energy of the torsion spring 23, the wire mesh plate 24 has the tendency to rotate in the opposite direction, so that the retaining ring 32 is locked into the hook groove 31 on the top block 3, thereby fixing the position of the wire mesh plate 24 and completing the sealing of the top of the hopper 1.

[0033] After hoisting is completed, the user only needs to press the top block 3 to disengage the retaining ring 32 from the hook groove 31, thereby rotating the wire mesh plate 24 away from the top center of the hopper 1, so that the material filled in the hopper 1 can be taken out.

[0034] This device, through the arrangement and cooperation of the fixed shaft 2, wire mesh plate 24, and torsion spring 23, utilizes the torsional potential energy accumulated by the torsion spring 23 after the side locking block 25 and positioning block 26 come into contact, and cooperates with the locking ring 32 to engage in the hook groove 31, successfully achieving rapid and efficient sealing of the top of the hopper 1. This prevents the material filled in the hopper 1 from slipping due to external factors during the hoisting process, greatly improving the safety of the hoisting process.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
