Description

Technical Field

[0001] This utility model relates to the field of high-altitude work technology, specifically a safety protection device for working at heights. Background Technology

[0002] Implementing fall protection measures for high-altitude operations involving oil unloading at oil depots is of paramount importance. While fall protection devices typically include safety belts and ropes, these are not suitable for oil unloading operations. With advancements in modern technology, the definition of safety belts and ropes has expanded beyond traditional concepts to include speed-differential self-controlled fall arresters, rail-mounted fall arresters, and more.

[0003] Before working at height, it is usually necessary to erect columns at the work location and then install truss steel structures on the columns so that the traction ropes on the truss steel structures can be attached to the workers to prevent them from falling from height. Because the truss steel structures are relatively heavy and installed at a relatively high position, large lifting equipment is usually required, which results in high costs.

[0004] Therefore, we propose a safety operation protection device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a safety operation protection device, comprising a column installed on the ground, a traction rope installed on the column, a pulling component installed at one end of the traction rope, and the other end of the traction rope connected to a lifting seat slidably installed inside the column. The lifting seat extends to the outside of the column and is detachably installed with a truss steel structure, and a fall arrestor is installed on the truss steel structure.

[0007] Furthermore, the bottom of the column is fixed with a base, and the base has several mounting holes.

[0008] Furthermore: the pulling assembly includes brackets symmetrically fixed on the base, and the same take-up reel is rotatably mounted between the two brackets, and one end of the traction rope is fixed to the take-up reel, and a motor is mounted through one end of the take-up reel through the bracket.

[0009] Furthermore: a U-shaped rod is installed on the inner top wall of the column, and a pulley is rotatably installed on the U-shaped rod. The other end of the traction rope passes through the pulley and is fixedly connected to the top of the lifting seat.

[0010] Furthermore, a "V"-shaped baffle is installed on the inner side wall of the column along a straight direction, and the traction rope is located inside the "V"-shaped baffle.

[0011] Furthermore: the lifting seat includes a sliding column slidably installed inside the column, and a mounting plate extending to the outside of the column is installed on the sliding column.

[0012] Furthermore: the truss steel structure includes a slide rail and a reinforcing rod located on the upper part of the slide rail, and the slide rail and the reinforcing rod are connected by several connecting rods. One end of the slide rail and one end of the reinforcing rod are fixed with a mounting plate, and each mounting plate is connected to the mounting plate by several bolts.

[0013] Furthermore: a movable plate is slidably installed inside the slide rail, and several mounting seats are fixed at the bottom of the movable plate, and the upper part of the fall arrestor is installed on the mounting seats.

[0014] The beneficial effects of this utility model are:

[0015] This utility model includes a lifting seat, a traction rope, and a pulling component inside the column. After the truss steel structure is installed on the upper part of the lifting seat, on the one hand, the pulling component can drive the lifting seat upward through the traction rope, and the lifting seat can drive the truss frame structure upward, thereby allowing the height of the truss steel structure to be adjusted according to the user's needs, improving the effectiveness of the device; on the other hand, it can directly drive the truss steel structure upward, eliminating the need for lifting equipment to install the truss steel structure, thus reducing the cost of truss steel structure installation.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] Embodiments of this utility model:

[0025] A safety protection device for work includes a column 1, a base 7 fixed to the bottom end of the column 1, and a plurality of mounting holes provided on the base 7, which can be fixed to the ground by bolts passing through the mounting holes, thereby reinforcing the column 1 and reducing the phenomenon of the column 1 tilting or collapsing.

[0026] A pulling assembly 3 is installed on the column 1. Specifically, the pulling assembly 3 includes two brackets 31 symmetrically fixed on the column 1, and a take-up reel 32 is rotatably mounted between the two brackets 31. One end of the take-up reel 32 passes through the bracket 31 and is fitted with a motor 33. The motor 33 drives the take-up reel 32. A traction rope 2 is fixed on the take-up reel 32, and the other end of the traction rope 2 extends into the interior of the column 1 and passes through a pulley 9, which is fixedly connected to the top of the sliding column 41. It should be noted that the pulley 9 is rotatably mounted on a "U"-shaped rod 8, and both ends of the "U"-shaped rod 8 are fixedly connected to the inner top wall of the column 1. Next, it should be noted that: a "V"-shaped baffle 10 is installed on the inner side wall of the column 1 along the straight direction, and the traction rope 2 is located inside the "V"-shaped baffle 10. The "V"-shaped baffle 10 serves to block the traction rope 2 and prevent the traction rope 2 from interfering with the up and down movement of the sliding column 41. A sliding groove is opened on the column 1 along the straight direction, and an installation plate 42 is fixed through the sliding groove on one side of the sliding column 41. A truss steel structure 5 is detachably installed on the installation plate 42, so that the truss steel structure 5 and the column 1 can be disassembled, which can reduce the area occupied by the installation of the protective device, facilitate transportation, and provide convenience for transportation personnel.

[0027] Specifically: The truss steel structure 5 includes a slide rail 51 and a reinforcing rod 52 located on the upper part of the slide rail 51. The slide rail 51 and the reinforcing rod 52 are connected by several connecting rods 53. The reinforcing rod 52 and several connecting rods 53 are used to reinforce the slide rail 51 and prevent collapse. One end of the slide rail 51 and one end of the reinforcing rod 52 are fixed with mounting plates 54. Each mounting plate 54 is connected to the mounting plate 42 by several bolts, so that the truss steel structure 5 can be disassembled. A movable plate 55 is slidably installed inside the slide rail 51. Several mounting seats 56 extending to the outside of the slide rail 51 are fixed at the bottom of the movable plate 55. A fall arrestor 6 is installed on the mounting seat 56 so that the fall arrestor 6 can be hung on the safety belt of the worker to prevent the worker from falling from a height.

[0028] When setting up the safety protection device, the staff first installs the column 1 on the ground and fixes it to the ground by passing bolts through the mounting holes. Then, the two mounting plates 54 can be installed on the same mounting plate 42 to secure the truss steel structure 5. Then, the motor 33 is turned on. The output shaft of the motor 33 drives the take-up reel 32 to rotate, so that the take-up reel 32 can take in the traction rope 2. The other end of the traction rope 2 can drive the lifting seat 4 to move upward. The lifting seat 4 can drive the truss steel structure 5 to move upward. When the truss steel structure 5 moves to the designated height, the motor 33 can be turned off.

[0029] When workers are working at heights, the fall arrestor 6 can be attached to their safety belt to prevent them from falling and to protect them.
