As shown in fig. 1, the automatic rope locking device of the two-level lever comprises a rope tube main body 1 with a cuboid structure, wherein a rope hole 101 penetrating through the rope tube main body 1 is formed in the middle of the rope tube main body 1, and the rope hole 101 is used for a safety rope to penetrate through. An opening 102 communicating with the rope hole 101 is formed in one side wall of the rope tube main body 1, the length direction of the opening 102 extends toward both ends of the rope tube main body 1, and the length of the opening 102 is close to the length direction of the rope tube main body 1. The rope tube comprises a rope tube body 1, wherein a rope locking plate 2 corresponding to an opening 102 is arranged on the side of the opening 102 of the rope tube body 1, a protrusion 201 which can extend into the inner side of the opening 102 is arranged on the side, close to the opening 102, of the rope locking plate 2, a first support 103 is arranged on the lower portion, close to the opening 102, of the rope tube body 1, the lower end of the rope locking plate 2 is hinged to the first support 103, and the rope locking plate 2 can rotate around a hinge point with the first support 103. When the rope locking plate 2 is parallel to the rope tube main body 1, the protruding 201 part can penetrate through the opening 102 and extend into the rope hole 101 to press the safety rope in the rope hole 101.
The lower part of rope pipe main part 1 is provided with one-level lever 3, and one-level lever 3 is U-shaped structure, and one-level lever 3 is articulated with the tip of the first support 103 that rope locking board 2 kept away from rope pipe main part 1 one side, and the free end of the both sides wall of one-level lever 3 is articulated with the lower extreme of second grade lever 4, and rope locking board 2 is located between second grade lever 4 and rope pipe main part 1. The free end of the primary lever 3 is provided with a bending part which bends downwards at a right angle, and the free end of the bending part is hinged with the lower end of the secondary lever 4. The hinge point of the primary lever 3 and the secondary lever 4 is located below the hinge point of the primary lever 3 and the first bracket 103.
The lower end of the rope tube main body 1 passes through the space between the two side walls of the primary lever 3, and the two side walls of the primary lever 3 are positioned at the two sides of the rope tube main body 1. The length of the primary lever 3 on the opening 102 side of the rope tube main body 1 is smaller than the length of the primary lever 3 on the other side of the rope tube main body 1.
The second bracket 104 is provided at the upper part of the rope tube main body 1 on the opening 102 side, and the upper part of the secondary lever 4 is hinged with the end part of the second bracket 104. A spherical pressure head 401 is arranged at one side of the upper end of the secondary lever 4 facing the rope locking plate 2, and the pressure head 401 can be in contact with the outer side of the rope locking plate 2.
A plurality of safety belt hanging holes 301 are arranged on the primary lever 3 on one side of the rope tube main body 1 opposite to the rope locking plate 2, and the safety belt hanging holes 301 are uniformly distributed at intervals along the length direction of the primary lever 3. The seat belt hanging hole 301 is used to cooperate with a seat belt on the operator.
The working principle of the invention is as follows:
the device mainly comprises two parts, namely a rope locking pipe main body 1 and a rope locking plate 2 are part, the other parts are a primary lever 3 and a secondary lever 4 which are pressing members, the primary lever 3 transmits multiplied pressure to the secondary lever 4, the secondary lever 4 transmits multiplied pressure to the rope locking plate 2, and finally, the overlapped pressure of the two levers is transmitted to the rope locking plate 2, and the rope locking plate 2 locks the safety rope.
Working principle: when downward pressure is applied to the free end of the primary lever 3, the hinge between the primary lever 3 and the first bracket 103 rotates, so that the other end of the primary lever 3 moves leftwards, namely clockwise, the primary lever 3 is hinged with the lower end of the secondary lever 4, the rotation of the primary lever 3 drives the lower end of the secondary lever 4 to move leftwards, namely the secondary lever 4 rotates around the hinge point of the secondary lever 4 and the primary lever 3, and the upper end of the secondary lever 4 moves rightwards.
The upper end of the secondary lever 4 rotates clockwise to push the rope locking plate 2 to rotate clockwise, the safety rope is pressed by the rope locking plate 2, and one side surface of the rope locking plate 2 is embedded into the rope tube main body 1 to be in close contact with the safety rope. The pressure transmitted to the rope locking plate 2 by the upper part of the secondary lever 4 fully presses the safety rope, so that the safety rope is locked and cannot be drawn. If the rope is required to be loosened, the free end of the primary lever 3 is lifted upwards, and the primary lever 3 drives the secondary lever 4 to cancel the pressure on the rope locking plate 2, so that the safety rope is loosened.
In actual use, the primary lever 3 is provided with a safety belt hanging hole 301, after an operator carries the safety belt, a hook of the safety belt is hung on the safety belt hanging hole 301, and if a human body falls off in a high altitude in a out-of-control manner, the free end of the primary lever 3 is automatically pulled by the self weight of the human body to incline downwards. The secondary lever 4 is driven to press the rope locking plate 2 of the rope locking device. The safety rope is locked by the rope locking plate 2, so that an operator can be automatically locked on the safety rope by the safety belt to ensure that the safety rope cannot fall downwards.
The rope locking device is mainly used for safety protection of high-altitude operators, such as construction of high-altitude building outer wall engineering, maintenance and scrubbing engineering of glass wall, high-altitude cable erection engineering, high-altitude rescue, danger elimination and other works. The portable electric heating device has the advantages of very wide application, small volume, light weight, portability and very safe and reliable use.
The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
