Abstract

The invention aims to solve the technical problem of providing a multifunctional follow-up rope grab, which adopts the technical scheme that: a multifunctional follow-up rope grabbing device comprises a rope groove and a speed limiter. When the person goes upwards, the rope grabbing device connected with the safety belt of the person goes upwards along the rope; when going downwards, the person drags the rope grab to go downwards along the rope. When the personnel descend and exceed the speed limit, the overspeed governor triggers and grabs the rope, reaches the purpose that prevents personnel's falling. When the rope is installed in a different system than the present invention, the present invention can be a descender, an ascender or a sheave for the rope, respectively.

Description

Multifunctional follow-up rope grabbing device

Technical Field

The present invention is a safety device classified as a device for ascending or descending persons from a building or the like, or a device for descending a rope, which is used in a62B1-06, in a class a62B 1-00. In particular to a rope appliance suitable for fiber ropes.

Background

Currently, existing aerial work equipment is mainly aerial work safety belts, which are relatively simple in structure, mainly consist of belts and metal fittings, and are fixed to ropes through the metal fittings. When the high-altitude operation position needs to be moved up and down, the metal fittings need to be moved manually. Although some rope grab devices can automatically go down by depending on the self-weight of the rope grab devices, in the process of the person going down, once the person loses weight, the rope grab devices can trigger the rope grab only after the person going down speed is higher than the down speed of the rope grab devices for a period of time, obviously, the rope grab distance of the rope grab devices is longer, and the impact force on the person is larger. The rope grabbing device automatically descends by means of dead weight, whether descending is smooth or not and the sensitivity of triggering rope grabbing are contradictory, if descending is smooth, the sensitivity of triggering rope grabbing is poor, and the rope grabbing distance is long; if the rope grabbing sensitivity is high, the rope grabbing is often triggered accidentally and the rope is not smooth to descend. Therefore, it is necessary to design a rope grab which can follow up. In field work, the fewer and lighter the rope appliances to be carried, the better it is of course if a rope appliance, such as a rope grab, can be used both as a people descender and as a people ascender and also as a pulley.

Further: the upper right of the upper sheet (17) is provided with a round hole, the lower right is provided with a round hole, the middle part is provided with an arc-shaped open slot, the upper right of the bottom sheet (11) is provided with a round hole, the lower right is provided with a round hole, the upper right of the middle sheet (19) is provided with a round hole, the middle part is provided with an arc-shaped open slot, the upper left of the right sheet (1) is provided with a slot, the upper right is provided with sawteeth, the lower edge is provided with teeth, the upper left of the left sheet (10) is provided with a slot, the upper right is provided with sawteeth, the lower edge is provided with teeth, the center of the ratchet wheel (3) is provided with a hole, the gear teeth are provided with a bulge, the middle of the limiting wheel (6) is provided with a hole, and the periphery is provided with 3 angles. Further: the middle plate (19) is connected with the bottom plate (11) by a sixteen (16) bolt, the upper plate (17) is connected with the middle plate (19) by a eighteen (18) bolt, a twelve (12) bolt is screwed into the bottom plate (11), penetrates through the groove of the right plate (1), penetrates through the groove of the left plate (10) and penetrates through the arc-shaped open slot of the upper plate (17), a thirteen (13) bolt is screwed into the bottom plate (11), penetrates through the arc-shaped open slot of the middle plate (19) and penetrates through the arc-shaped open slot of the upper plate (17), a fourteen (14) bolt is screwed into the bottom plate (11) and penetrates through the arc-shaped open slot of the middle plate (19), a fifteen (15) bolt is screwed into the bottom plate (11) and penetrates through the arc-shaped open slot of the middle plate (19), a four (4) bolt is screwed into the right plate (1), penetrates through the middle hole of the limiting wheel (6) and is screwed into the left plate (10), a five (5) bolt is screwed into the right plate (1) and then into the left plate (10), the bolt nine (9) is screwed into the right piece (1), passes through the central hole of the ratchet wheel (3) and is screwed into the left piece (10). Further: one end of a second tension spring (2) is connected with the seventh bolt (7), the other end of the second tension spring is connected with the upper corner of the limiting wheel (6), one end of an eighth tension spring (8) is connected with the lower part of the bottom sheet (11), and the other end of the eighth tension spring is connected with the seventh bolt (7). Further: the seventh bolt (7) is limited in one sawtooth of the right sheet (1), and the other end of the seventh bolt is limited in the sawtooth of the left sheet (10).

Further, the above embodiment of the present invention, when used as a follow-up rope grab, is specifically used as follows: the right hand holds the bottom plate (11) and pushes the speed limiter upwards by using the thumb, the left hand rotates the upper plate (17) and the middle plate (19) anticlockwise, the rope is placed in the rope groove, the right hand thumb releases the speed limiter, and the left hand rotates the middle plate (19) and the upper plate (17) clockwise until the arc-shaped open groove of the upper plate (17) blocks the bolt twelve (12). The lock catch on the safety belt of the person is used for connecting the upper round holes of the upper sheet (17), the middle sheet (19) and the bottom sheet (11). When personnel go upward, personnel's accessible drives with the safety rope that grabs the rope ware and go upward, when personnel normally go down, rope in the grooving drives ratchet (3) and rotates, the teeth of a cogwheel of ratchet (3) drive the left corner of spacing wheel (6) and overcome the pulling force rotation of extension spring two (2), when rotating to certain angle, the teeth of a cogwheel of ratchet (3) leave spacing wheel (6) left corner, initial position is got back to under the effect of extension spring two (2) to spacing wheel (6), wait for next teeth of a cogwheel to drive spacing wheel (6) left corner and rotate. When personnel down speed was too fast, initial position had not been got back to spacing wheel (6) under the effect of extension spring two (2), the next teeth of a cogwheel of ratchet (3) have caught the upper corner of spacing wheel (6), stall after bolt five (5) were touch to spacing wheel (6) lower corner, ratchet (3) also stall, the overspeed governor is under the drive of rope, overcome the pulling force of extension spring eight (8), move up right along bolt twelve (12), and clockwise rotation, the tooth of right side piece (1) and left side piece (10) lower part seizes the rope under the effect of extension spring eight (8), reach and grab the rope and prevent the mesh that weighs down.

Furthermore, when the position of the movable bolt seven (7) changes the elastic deformation length of the tension spring two (2), the speed threshold value of the speed governor can be changed. When the upper part of the rope penetrates out of the middle of the bolt thirteen (13) and the bolt fourteen (14) to the left, the lock catch on the safety belt of a person penetrates through the upper round holes of the upper piece (17), the middle piece (19) and the bottom piece (11), and the rope can be used as a descender. When the rope only passes through the bolt fifteen (15), and the lock catch passes through the upper round holes of the upper sheet (17), the middle sheet (19) and the bottom sheet (11) and is connected with the anchor point, the invention is used as a pulley. When the speed limiter moves upwards relative to the bolt twelve (12) and rotates clockwise until the teeth of the ratchet wheel (3) do not touch the rope, the speed limiter serves as a raiser.

The present invention is not limited to the above embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof are within the protection scope if they have the same or similar technical solutions as the present invention.
