Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings.

As shown in fig. 1-2, a novel buffering seat structure of knapsack frame elevator, comprising a bottom plate 1, waist holes 2 are respectively formed in two ends of the bottom plate 1, a top plate 3 and two supporting plates 4 used for connecting the top plate 3 and the bottom plate 1 are arranged above the bottom plate 1, through holes are formed in the upper surface of the top plate 3, a sleeve 5 communicated with the through holes is arranged on the top plate 3, a push rod 6 is slidably connected in the sleeve 5, a pressing plate 7 is arranged at the upper end of the push rod 6, a compressible damping block 8 is arranged on the upper surface of the pressing plate 7, a baffle 9 is arranged at the lower end of the push rod 6, a spring 10 is sleeved on the outer surface of the sleeve 5 and is located between the top plate 3 and the pressing plate 7, and a compressible damping column 11 is arranged on the upper surface of the bottom plate 1 and located under the baffle 9.

The knapsack frame elevator includes guide rail support, car and control car power system and other safety module that remove, this buffer seat installs in guide rail support's bottom upper surface, specifically, the waist hole 2 on accessible bolt and the bottom plate 1 is with this buffer seat installs in guide rail support's bottom upper surface, the car can reciprocate along guide rail support, the lateral part of car surface is provided with the fixed plate, the car during normal work, the fixed plate of car lateral part can not contact with the buffer seat, only when the car appears uncontrolled whereabouts, the fixed plate of car surface can only be when falling to certain position, with the lower buffer seat contact of mounted position, thereby avoid car and ground hard contact.

When uncontrolled whereabouts appear in the car and the fixed plate of car surface moves to certain position along with the car, the fixed plate can at first contact with snubber block 8, snubber block 8 compresses after being pressed, will transmit to clamp plate 7 department in will simultaneously, clamp plate 7 after being pressed, can promote ejector pin 6 and move down, make spring 10 compress simultaneously, and spring 10 can promote roof 3 and move down at the in-process of compressing, roof 3 can appear crooked at the in-process of moving down, backup pad 4 when crooked to a certain degree, the dog can contact with shock strut 11, and make shock strut 11 compress, avoid the dog to be in hard contact with bottom plate 1, in order to play the effect of further buffering.

The compression of the damping block 8 can play a first buffering role for the car to reduce the impact force when the car falls, the compression of the spring 10 can play a second buffering role for the car to further reduce the impact force when the car falls, the bending of the supporting plate 4 can play a third buffering role for the car to continuously reduce the impact force when the car falls, the bending of the damping column 11 can play a fourth buffering role for the car to realize the final buffering of the car, compared with the existing buffer seat, the impact force when the car falls can be gradually reduced through multistage repeated buffering, and the reduction capability of the damping block 8, the spring 10 and the supporting plate 4 to the impact force of the car is gradually enhanced to improve the safety of passengers in the car.

Meanwhile, when the shock absorption column 11 is extruded by the stop block and the shock absorption column 11 cannot be further compressed by the impact force of the car, a certain distance still exists between the lower surface of the car and the ground, so that passengers in the car can be better protected.

The shock absorption block 8 and the shock absorption column 11 are made of polyurethane.

Further, the support plate 4 is set to be arc, the support plate 4 has arc protruding face and interior concave surface, and the interior concave surface on two protruding faces all is located between two protruding faces, and when the support plate 4 is pressed and is warp, the support plate 4 can be crooked to the direction of protruding face to avoid the direction bending of the interior concave surface of support plate 4 to influence the buffering of shock strut 11 to the dog as far as possible.

Further, the clamp plate 7 and the roof 3 are rectangular plate-shaped structures, the support plate 4 is in the process of being pressed and bent, the roof 3 and the clamp plate 7 are rectangular plate-shaped structures all the time, the support plate 4 and the clamp plate 7 are high-strength steel plates, the thickness is 16mm, the thickness and the strength of the support plate 4 and the clamp plate 7 are higher than those of the support plate 4, and therefore the buffer structure can be ensured to be extruded downwards when being pressed, the occurrence of skew conditions is reduced, and effective buffering is ensured.
