Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of lifting systems, and in particular relates to a safety anti-fall structure for an underground lifting system. Background Technology
[0002] A buried waste collection station is a device that installs waste recycling equipment underground. It consists of two layers: the upper layer is flush with the ground and has an aesthetically pleasing design, and is equipped with a feeder; the lower layer houses the compaction station and is located underground. When replacing a waste bin or waste station, the entire buried waste station is raised, the waste bin or waste station is pulled out, and a new waste bin or waste station is installed.
[0003] When the underground station is raised, it is pulled upwards relative to the underground lifting system column by a main hydraulic cylinder at the bottom, which works in conjunction with steel wire ropes and multiple pulleys. However, during the lifting operation, the underground station may fall due to the failure of some mechanisms, such as a broken steel wire rope or a pulley that the steel wire rope has passed over coming off. Therefore, it is necessary to design a relatively simple protective device to prevent the underground station from suddenly falling, in order to protect the safety of personnel and property. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a safety anti-fall structure for an underground lifting system, addressing the shortcomings of the existing technology.

[0006] A safety anti-fall structure for an underground lifting system includes an anti-fall rack installed on the upright of the underground lifting system and an anti-fall lock structure installed on the main lifting beam of the underground lifting system. The anti-fall lock structure includes a lock frame body, a hinge seat, an anti-fall lock, and a spring. The lock frame body is fixed to the main lifting beam of the underground lifting system, the hinge seat is fixed to the lock frame body, the anti-fall lock is hinged to the hinge seat in the middle, the upper end of the anti-fall lock is connected to a steel wire rope, and the other end of the steel wire rope is connected to an external power source. The external power source can move the main lifting beam up and down relative to the upright by pulling the steel wire rope. The lower end of the anti-fall lock is connected to one end of a spring. The other end is fixed to the main body of the lock frame. The steel wire rope has an upward pulling force on the anti-fall lock, keeping the anti-fall lock in a vertical state. The spring has the potential energy to push the lower end of the lock frame body laterally, causing the anti-fall lock to have a tendency to rotate horizontally around the hinge seat. Several anti-fall teeth are set on the anti-fall rack along the vertical direction. There is a horizontal gap between the anti-fall rack and the anti-fall lock structure. When the anti-fall lock rotates horizontally, the lower end of the anti-fall lock can be screwed into the anti-fall teeth and contact the anti-fall teeth, and the upper end of the anti-fall lock can contact the main body of the lock frame, thereby fixing the underground lifting system column and the underground lifting system lifting main beam together.

[0008] The anti-falling lock structure further comprises a spring seat, which is fixedly installed at the lower end of the lock frame body and away from the side of the buried lifting system column, and the other end of the spring is fixed on the spring seat.
[0009] The spring seat and the lower end of the lock frame body are connected through a horizontal adjusting screw rod, the length of the adjusting screw rod can be changed by rotating into the lock frame body, thereby changing the horizontal distance between the spring seat and the lower end of the lock frame body, and the compression degree of the spring is changed.
[0010] The upper end of the anti-falling lock is provided with a lock groove, the lower end of the steel wire can be inserted into the lock groove, the anti-falling lock further comprises a rope buckle stopper and a safety baffle, the rope buckle stopper can be inserted into the lock groove to position the lower end of the steel wire in the lock groove, and the safety baffle is fixed outside the lock groove to fix the rope buckle stopper in the lock groove.
[0011] The safety baffle and the upper end of the anti-falling lock are both provided with threaded holes, and a screw is inserted into the threaded holes to fixedly connect the safety baffle and the upper end of the anti-falling lock.
[0012] The upper end of the lock frame body is fixed with a main beam support foot, and the main beam support foot is fixedly connected with the lower end of the lifting main beam of the buried lifting system through bolts.
[0013] The connection between the main beam support foot and the lock frame body is provided with a reinforcing rib.
[0014] The tooth tip of the anti-falling tooth is upward, the bottom of the anti-falling lock is provided with a groove, and when the anti-falling lock is in contact with the anti-falling tooth, the tooth tip of the anti-falling tooth is located in the groove in the bottom of the anti-falling lock.
[0015] The anti-falling tooth strip is welded and fixed on the buried lifting system column.
[0016] The anti-falling lock and the anti-falling tooth strip are both made of steel material.
[0017] The anti-falling lock and the anti-falling tooth strip are both made of steel material.
[0018] 1、The anti-falling tooth strip is installed on the buried lifting system column, the anti-falling lock structure is installed on the lifting main beam of the buried lifting system, the anti-falling lock is connected with the steel wire, the power system transmits power to the anti-falling lock through the steel wire, the anti-falling lock transmits power to the lifting main beam of the buried lifting system, so that the buried station is lifted, and when the buried station suddenly falls during the lifting process, the steel wire inevitably loses the pulling force on the anti-falling lock structure, the anti-falling lock rotates under the action of the spring, and then the lower end of the anti-falling lock is inserted into the anti-falling tooth of the anti-falling tooth strip and in contact with the anti-falling tooth, and the upper end of the anti-falling lock is in contact with the lock frame body, the inclined anti-falling lock is connected between the buried lifting system column and the lifting main beam of the buried lifting system as a fixing piece, so that the lifting main beam of the buried lifting system is prevented from continuing to descend, and the safety of personnel and property is effectively protected.
[0019] 2、The spring seat and the lower end of the lock frame body are connected through the horizontal adjusting screw rod, the length of the adjusting screw rod can be changed by rotating into the depth of the lock frame body, thereby changing the horizontal distance between the spring seat and the lower end of the lock frame body, adjusting the distance between the spring and the lower end of the anti-falling lock, and realizing the adjustment of the spring force. The utility model can ensure that the anti-falling lock can quickly pop out when the steel wire rope loses tension by adjusting the spring force, realize the self-locking of the ground burying lifting system, and also prevent the spring force from being too large, the bottom of the anti-falling lock from protruding outward, and the normal lifting of the ground burying station from being affected.

[0032] As Figures 1-3 Shown, anti -fall lock structure 3 mainly includes lock frame main body 31, articulated seat 32, anti -fall lock 33, spring 34, spring seat 35, main beam support leg 36, reinforcing rib 37 and the like structure, and the upper end of lock frame main body 31 is fixed on the bottom of the ground -buried lifting system lifting girder 2 through main beam support leg 36, and the connecting portion is bolted, and reinforcing rib 37 is arranged on main beam support leg 36 to improve the connecting strength. Articulated seat 32 is installed in the middle of lock frame main body 31, and anti -fall lock 33 is hinged on articulated seat 32 through a hinge shaft in the middle, and anti -fall lock 33 can rotate around the hinge shaft, when the lower end of anti -fall lock 33 rotates 30 ° to the direction of the ground -buried lifting system column 1, the lower end of anti -fall lock 33 will stretch into the anti -fall tooth 41 of anti -fall rack 4, and the upper end of anti -fall lock 33 will also be against lock frame main body 31. A lock groove 33a is formed in the upper end of anti -fall lock 33, and the side surface and top of lock groove 33a are both opened on the surface of anti -fall lock 33, the end of steel wire rope 5 is provided with a buckle, is put into lock groove 33a from the side, and the upper end of lock groove 33a is small and cannot let the end of steel wire rope 5 pass through the buckle, then the rope buckle stopper 33b is used to block the side opening of lock groove 33a, so that the end of steel wire rope 5 is fixed on the upper end of anti -fall lock 33, and the safety baffle 33c is fixed outside lock groove 33a by screw, and the rope buckle stopper 33b is fixed in lock groove 33a. Spring seat 35 is fixedly installed on the side, away from the ground -buried lifting system column 1, of the lower end of lock frame main body 31, and spring seat 35 and the lower end of lock frame main body 31 are connected through horizontal adjusting screw 35a, the length of adjusting screw 35a can be changed by rotating into the depth of lock frame main body 31, and then the horizontal distance between spring seat 35 and the lower end of lock frame main body 31 is changed, one end of spring 34 is connected with the lower end of anti -fall lock 33, and the other end is fixed on spring seat 35, and the bottom of anti -fall lock 33 is provided with a groove, and the groove is used for matching the sharp part of anti -fall tooth 41.

[0035] like Figure 6 As shown, when the main cylinder, wire rope 5, and other structures suddenly fail, the force of the wire rope 5 pulling the anti-fall lock structure 3 upward disappears. At this time, the compressed spring 34 will extend, pushing the lower end of the anti-fall lock 33 towards the underground lifting system column 1, thereby causing the lower end of the anti-fall lock 33 to extend into the anti-fall tooth 41 of the anti-fall rack 4. The upper end of the anti-fall lock 33 abuts against the lock frame body 31, and the anti-fall lock 33 becomes a diagonal brace, supporting the underground lifting system column 1 and the underground lifting system lifting main beam 2, preventing the underground lifting system lifting main beam 2 from moving downward, thereby avoiding the sudden fall of the entire underground station lifting platform and protecting the safety of personnel and property.
