[0002] During the construction of a double-shield TBM (Tunnel Boring Machine, i.e., full-face hard rock tunnel boring machine), the diameter of the tunnel wall excavated by the cutter head is larger than the outer diameter of the segment. After the segment is assembled and installed, a gap will be formed between the segment and the tunnel wall. In order to ensure the stability of the segment installation and the safety of tunnel construction, it is necessary to first blow pea gravel into the gap between the segment and the tunnel wall and then backfill and grouting are performed to keep the segment stable.

[0003] The pea gravel used for filling needs to be transported from the ground to the excavation shaft for use. The current method is usually to transport the pea gravel tank filled on the ground by a rail transport vehicle to the side of the pea gravel conveying skirt belt conveyor in the excavation shaft, and then manually lift it by a hand winch to the bracket above the pea gravel conveying belt conveyor. This is time-consuming and labor-intensive, and the manual lifting process is prone to shaking due to the large volume and weight of the tank filled with pea gravel, which can easily cause safety hazards. Therefore, it is necessary to design a safe and efficient pea gravel tank lifting crane to solve the existing problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5As shown, the utility model is a crane for lifting a bean gravel tank, comprising a traveling frame 2, a vertical lifting mechanism and a transverse mechanism 8, wherein the vertical lifting mechanism is arranged on the traveling frame 2, the transverse mechanism 8 is fixedly mounted on the transverse side ends of the traveling frame 2, and the traveling frame 2 is erected on the cross beams on both sides of the trolley 1 through the transverse mechanism 8, wherein, when the bean gravel tank 9 is transported to a predetermined lifting position by a rail trolley, the bean gravel tank 9 is lifted to a preset height by the vertical lifting mechanism, and the traveling frame 2 and the lifted bean gravel tank 9 are moved laterally as a whole to above the bracket by the transverse mechanism 8, so as to place the bean gravel tank 9 on the bracket again by the vertical lifting mechanism.

[0030] The loader 8 is used to lift the hopper 9 and the loader 8 is used to lift the hopper 9 to the desired height.

[0031] In this specific embodiment, the vertical lifting mechanism includes a lifting ring 6 for hanging and connecting the two ends of the bean gravel tank 9, the lifting ring 6 is fixedly connected to one end of the lifting chain 5, the other end of the lifting chain 5 is fixedly connected to the guide wheel group 3, the guide wheel group 3 is in a guiding sliding connection with the traveling frame 2, and the wheel axle ends on both sides of the guide wheel group 3 are respectively fixedly connected to the telescopic ends of the cylinder 4, and the cylinder 4 is fixedly installed on the traveling frame 2; wherein, a chain redirecting wheel group 7 spaced apart from the guide wheel group 3 is provided in the longitudinal straight direction of the traveling frame 2, and the chain redirecting wheel group 7 is used for guiding and contacting the lifting chain 5.

[0032] During the vertical lifting of the bean gravel tank 9, the two ends of the bean gravel tank 9 are respectively hung and fixedly connected by the lifting ring 6. When the oil cylinder 4 drives the guide wheel group 3 to extend, the guide wheel group 3 moves longitudinally along the traveling frame 2, so that the lifting chain 5 along the chain redirecting wheel group 7 lifts the bean gravel tank 9 to a preset height position. When the lifted bean gravel tank 9 is laterally transferred to above the placement position by the transverse movement mechanism 8, the guide wheel group 3 is retracted by the oil cylinder 4, so that the bean gravel tank 9 is conveniently lowered to the bracket, so as to realize the safe and efficient operation of vertically lifting the bean gravel tank 9.

[0033] It should be understood that the guide wheel group 3 and the chain redirecting wheel group 7 are arranged at intervals along the longitudinal straight line direction of the traveling frame 2, which can ensure that the lifting chain 5 always moves in a straight line with the guide wheel group 3 during the lifting of the bean gravel tank 9, thereby reducing the shaking of the lifting chain 5 during the lifting process and further enhancing the safety of lifting.

[0034] It should be understood that during the lifting of the bean gravel tank 9, the distance between the chain redirecting wheel sets 7 on both sides is greater than the frame distance of the bean gravel tank 9. Since the lifting rings 6 need to be put on the lifting rods at both ends of the bean gravel tank 9, the friction between the lifting chain 5 and the frame of the bean gravel tank 9 can be effectively prevented during the lifting process, thereby reducing the wear of the lifting chain 5 and the bean gravel tank 9.

[0035] In this specific embodiment, a chain roller 501 is provided in the middle position of the guide wheel group 3 and the chain redirecting wheel group 7. The chain roller 501 is used to support and resist the lifting chain 5, and the chain roller 501 is fixedly connected to the traveling frame 2. During the lifting of the bean gravel tank 9, the lifting chain 5 is prone to fall in the middle of the chain due to its own weight. In severe cases, the lifting ring 6 connected to the lifting chain 5 cannot fall smoothly, causing inconvenience in use. The present application supports and lifts the lifting chain 5 by providing the chain roller 501, which can ensure that the lifting chain 5 falls smoothly along the chain roller 501 and the chain guide wheel group 3 during the lifting process, which is convenient for lifting and use.

[0036] In this specific embodiment, the chain redirecting wheel set 7 is provided with a sprocket portion that meshes with the node ring of the lifting chain 5 to ensure that the lifting chain 5 is redirected stably at the position of the chain redirecting wheel set 7 to avoid the occurrence of redirection separation.

[0037] The traverse mechanism 8 in this specific embodiment includes a motor 801, a torque seat 802, a traverse roller 803 and a connecting plate 804. The connecting plate 804 is fixedly connected to the lateral side ends of the traveling frame 2. Both ends of the connecting plate 804 are rotatably connected to the traverse rollers 803. The traverse rollers 803 at both ends are respectively connected to the cross beams of the trolley 1 for guiding and sliding. One end of the traverse roller 803 is connected to the motor 801 through a reducer. The motor 801 is fixedly installed on the traveling frame 2 through the torque seat 802. The torque seat 802 can offset the torque during the rotation of the motor 801 to reduce vibration. When the hoisted bean gravel tank 9 is transferred laterally, it is convenient to drive the traverse roller 803 to rotate through the motor 801, so that the traverse roller 803 moves along the cross beam of the trolley 1, thereby facilitating the traverse frame 2 and the hoisted bean gravel tank 9 to be moved laterally as a whole to the top of the bracket, so that the bean gravel tank 9 can be placed on the bracket again through the vertical lifting mechanism. The operation is convenient, safe and efficient.

[0038] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
