Description

Technical Field

[0001] The utility model belongs to the technical field of large equipment transportation, and particularly relates to a fixing device for the transportation of a reaction tower. Background Technique

[0002] Reaction towers are widely used equipment in chemical production, such as reaction towers for organic and inorganic substances like urea synthesis towers and ammonia synthesis towers. During the transportation of reaction towers, they are restricted by parameters such as the weight of the tower body (the reaction tower has a large size and length and is made of metal), and in current transportation methods, the bridge beam transportation method is mostly adopted, that is, the reaction tower is placed horizontally in a large transportation vehicle and fixed before being transported. It is generally composed of two rows of axis vehicles arranged separately front and back and a set of intermediate bearing beams, dividing the weight of the large-size heavy synthetic tower into two equal parts and evenly loading them onto the front and rear axis vehicles.

[0003] Before transporting using the above method, it is necessary to ensure that the entire reaction tower is safely and firmly fixed on the vehicle body. Due to problems such as the large size and weight of the reaction tower, it is difficult to use the traditional method of fastening with ropes to ensure the safe fixation of the reaction tower. Therefore, for the transportation fixation of the reaction tower to avoid tremors and falling accidents of the reaction tower during transportation, it is urgent to design a fixing device to replace the traditional fixing method of rope bundling and achieve rapid and effective fixation of the reaction tower. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for the transportation of a reaction tower to solve the problems of difficult transportation fixation and complex operation of the reaction tower proposed in the above background technique. The following technical solutions are provided: A fixing device for the transportation of a reaction tower, comprising:

[0005] A bottom plate, inside which an installation groove is fixedly provided, in the middle of the installation groove, an operation box body is embedded, and an accommodation space is provided inside the operation box body;

[0006] A transmission component, slidably arranged at the upper end of the operation box body;

[0007] A fixing component, hinged at the upper end of the operation box body, and the two side ends of the transmission component are in inclined surface transmission with the lower end of the fixing component;

[0008] A reaction tower, embedded at the upper end of the fixing component.

[0009] The operation box body includes fixing ears, which are fixedly arranged at the end of the outer side wall of the operation box body, and the fixing ears are installed in the middle of the installation groove. In the middle of the bottom end wall of the operation box body, a guide rail is also fixedly provided, and the extending direction of the guide rail is the same as the extending direction of the operation box body.

[0010] In this technical solution, during the transportation of the reaction tower, a transportation method of horizontally placing the reaction tower is adopted. Both ends of the reaction tower have stepped heads for fixing the entire equipment during transportation.

[0011] When using this device, first, according to the length of the reaction tower, two pairs of opposed bottom plates are respectively fixed at both ends of the transport vehicle body. Then, the reaction tower is placed in the middle of the two bottom plates. By manually rotating the transmission component to drive the operation box body to move, during the movement of the operation box body, inclined plane transmission occurs between the operation box body and the fixing component, thereby driving the two fixing components to engage with each other, locking and fixing the cylindrical heads at both ends of the reaction tower, and achieving the fixation of the entire reaction tower.

[0012] In any of the above technical solutions, further, the transmission component includes a transmission block. The longitudinal section of the transmission block is trapezoidal, and both sides of the transmission block have arcs. A chute is provided at the lower end surface of the transmission block, and the chute is slidably arranged on the guide rail. A threaded hole is fixedly provided in the middle of the chute, and a lead screw is threadedly connected in the threaded hole.

[0013] One end of the lead screw is rotatably arranged at the end wall of the operation box body, and a handle is fixedly arranged at the end of the lead screw.

[0014] In this technical solution, a threaded transmission is adopted between the threaded hole and the lead screw. The operator can drive the lead screw and the handle to rotate by shaking the handle. The threaded transmission has a self-locking property, ensuring the stability of the moving position of the transmission block.

[0015] In any of the above technical solutions, further, the fixing component includes a cylindrical pin fixedly arranged at the end wall of the operation box body. A fixing claw is rotatably arranged in the cylindrical pin. There are two fixing claws arranged opposite to each other, and the upper ends are semi-arc-shaped, and they are engaged with each other to form an arc shape to lock the reaction tower.

[0016] A lever is fixedly arranged at the lower end of the fixing claw, and one end surface of the lever is always in contact with the side end inclined plane of the transmission block, used to drive the fixing claw to rotate around the cylindrical pin.

[0017] In this technical solution, during the horizontal movement of the transmission block, both sides of the transmission block come into contact with the lever. Since the overall shape of the transmission block is trapezoidal, at this time, as the transmission block moves, the two levers are pushed outwards. When the two levers move outwards simultaneously, the fixing claw rotates around the cylindrical pin, resulting in the continuous closing of the upper ends of the fixing claws. Finally, the two fixing claws are closed to form an arc shape to completely lock the reaction tower and complete the fixation of the reaction tower.

[0018] The beneficial effects of the present utility model are as follows: Through the provided transmission component and fixed component, the two are linked by means of inclined plane transmission. After the transmission between the transmission component and the fixed component, it is ensured that the fixed claw can be buckled to fix the reaction tower. The horizontal movement of the transmission component is realized by screw transmission, and the screw transmission can ensure the stability of the moving position of the transmission component. The operator can control the entire device by shaking the handle with the arm. The operation is simple, the rigidity of the entire device is large, and the fixing method is reliable.

[0027] The transmission component 30 is slidably arranged at the upper end of the operation box body 20;

[0028] The fixing component 40 is hinged at the upper end of the operation box body 20, and the two side ends of the transmission component 30 are in inclined surface transmission with the lower end of the fixing component 40;

[0029] The reaction tower 50 is embedded at the upper end of the fixing component 40.

[0030] The operation box body 20 includes fixing ears 21 which are fixedly arranged at the end of the outer side wall of the operation box body 20, and the fixing ears 21 are installed in the middle of the installation groove 11. In the middle of the bottom end wall of the operation box body 20, a guide rail 22 is also fixedly arranged, and the extending direction of the guide rail 22 is the same as the extending direction of the operation box body 20.

[0031] In this technical solution, during the transportation process of the reaction tower, a transportation method of horizontally placing the reaction tower 50 is adopted. The two ends of the reaction tower have stepped heads for fixing the entire equipment during transportation.

[0032] When using this device, first, the two opposite bottom plates 10 are respectively fixed at both ends of the transport vehicle body according to the length of the reaction tower, and then the reaction tower 50 is placed in the middle of the two bottom plates 10. By manually rotating the transmission component 30 to drive the operation box body 20 to move, during the movement of the operation box body 20, inclined surface transmission occurs between the operation box body 20 and the fixing component 40, thereby driving the two fixing components 40 to be buckled, and locking and fixing the two cylindrical heads at both ends of the reaction tower 50, realizing the fixation of the entire reaction tower.

[0033] In a relatively preferred embodiment of the present utility model:

[0034] As shown in FIGS. 2 and 4, specifically, the transmission component 30 includes a transmission block 31. The longitudinal section of the transmission block 31 is trapezoidal, and the two sides of the transmission block 31 have arcs. A chute 32 is provided at the lower end surface of the transmission block 31, and the chute 32 is slidably arranged on the guide rail 22. A threaded hole 33 is fixedly provided in the middle of the chute 32, and a lead screw 34 is threadedly connected in the threaded hole 33.

[0035] One end of the lead screw 34 is rotatably arranged at the end wall of the operation box body 20, and a handle 35 is fixedly arranged at the end of the lead screw 34.

[0036] In this technical solution, a threaded transmission is adopted between the threaded hole 33 and the lead screw 34. The operator can drive the lead screw 34 and the handle 35 to drive by shaking the handle 35. The threaded transmission has a self-locking property, ensuring the stability of the moving position of the transmission block 31.

[0037] In a preferred embodiment of the present utility model:

[0038] As shown in FIGS. 1, 2 and 4, specifically, the fixing component 40 includes a cylindrical pin 42 fixedly arranged at the end wall of the operation box body 20. A fixing claw 41 is rotatably arranged in the cylindrical pin 42. There are two fixing claws 41 arranged oppositely, and the upper ends thereof are semi-arc-shaped. They are buckled into an arc shape to lock the reaction tower 50.

[0039] A lever 43 is fixedly arranged at the lower end of the fixing claw 41, and one end surface of the lever 43 is always in contact with the side inclined surface of the transmission block 31, so as to drive the fixing claw 41 to rotate around the cylindrical pin 42.

[0040] In this technical solution, during the horizontal movement of the transmission block 31, the two sides of the transmission block 31 come into contact with the lever 43. Since the transmission block 31 is trapezoidal as a whole, at this time, as the transmission block 31 moves, the two levers 43 are pushed upwards to the outside. When the two levers 43 move to the outside at the same time, the fixing claw 41 rotates around the cylindrical pin 42, resulting in the upper ends of the fixing claws 41 closing continuously. Finally, the two fixing claws 41 are closed to form an arc shape to completely lock the reaction tower 50 and complete the fixation of the reaction tower.
