The force bearing frame 1 comprises a first rod body 11 and a second rod body 12. The first rod body 11 is used for being connected with a steel wire rope in a material lifting system; the two second rods 12 are respectively fixedly connected to two ends of the first rod 11, and the two second rods 12 are parallel to each other.
The sleeve 2 is disposed at the lower end of the second rod 12, and an end of the sleeve 2 facing the first rod 11 is open.
The spring 3 is sleeved on the second rod 12, and one end of the spring 3 is located in the sleeve 2 and is abutted to one end of the sleeve 2, which is far away from the first rod 11, when the spring 3 is in a natural extension state, the total length of the spring 3 is greater than that of the sleeve 2, and the spring is extended outwards from the opening end of the sleeve 2.
One end of the connecting rod 4 is hinged with the side wall of the sleeve 2, and the other end is hinged with the upper end part of the safety clamp 5. Wherein, during actual installation, the middle part of the connecting rod 4 is hinged in a container of the material lifting system, so that when the sleeve 2 is lifted, one end of the connecting rod 4 connected with the safety clamp 5 is lifted reversely.
It should be noted that the safety clamp 5 is a technical product purchased from elevator manufacturers, and the basic principle thereof is that when the connection point at the upper end of the safety clamp 5 is under tension, the two clamping plates approach to the middle to realize the clamping action.
When the braking device is installed in engineering equipment, the middle part of the connecting rod 4 is hinged in containers such as containers for containing materials, the upper end of the spring 3 is abutted against the top of the container, the steel wire rope is connected with the first rod body 11, when the container is pulled upwards, the sleeve 2 moves upwards under the action of the self weight of the container and the tension of the steel wire rope, the spring 3 is compressed, the connecting rod 4 swings, at the moment, two clamping plates of the safety clamp 5 are opened, and the whole equipment moves upwards; when the steel wire rope is broken or the equipment brake fails to cause the container to lose weight, the first rod body 11 loses tension, the spring 3 automatically extends to push the sleeve 2 to move downwards, meanwhile, the connecting rod 4 swings reversely to lift the connecting point at the upper end part of the safety clamp 5 upwards, the two clamping plates of the safety clamp 5 approach to the middle part to clamp the steel frame guide rail, and the container can stop falling. Through the cooperation of spring 3, sleeve 2 and connecting rod 4, the splint of control safety clamp 5 open and shut, and then reach the braking function, effectively avoided because of loss of property or casualties that the container free fall leads to.
Optionally, the first rod 11 is arranged in an inverted V shape, so that the first rod is conveniently connected with a steel wire rope.
Referring to fig. 1 and 2, as an alternative solution of the present application, a lower end portion of the second rod 12 is provided with a thread, a bottom surface of the sleeve 2, that is, a surface far away from the first rod 11 is provided with a through hole for the second rod 12 to pass through, and the second rod 12 is connected with a nut 13 through the thread after passing through the bottom surface of the sleeve 2. The nut 13 is connected with the second rod body 12, so that the brake device is more convenient to mount and dismount, the nut 13 is always abutted to the sleeve 2 in the using process of the brake device, when the first rod body 11 is pulled, the nut 13 abuts against the sleeve 2 to move upwards, and when the pulling force applied to the first rod body 11 is zero, the sleeve 2 abuts against the nut 13 to move downwards.
Meanwhile, it should be understood that the nut 13 also has the function of adjusting the elasticity of the spring 3, and the elasticity of the spring 3 can be controlled by rotating the nut 13 to change the length of the second rod 12 penetrating through the bottom surface of the sleeve 2.
Alternatively, the second rod 12 may be fixedly connected to the bottom surface of the sleeve 2, and the normal operation of the braking device may also be achieved, but the operability is low during the installation and removal of the device.
Referring to fig. 1, as an alternative solution of the present application, a support 21 is slidably connected to a side wall of the sleeve 2, the support 21 can be fixed by a bolt connection, and an end of the connecting rod 4 is hinged to the support 21. After the braking device is installed in the container, the initial position of the connecting rod 4 can be adjusted by adjusting the position of the support 21, thereby facilitating the control of the opening and closing of the clamping plates of the safety clamp 5.
Referring to fig. 1, as an alternative solution of the present application, a limiting ring 14 is disposed at an upper end of the second rod 12, and the limiting ring 14 can limit a downward moving distance of the second rod 12, and is matched with a stroke of the safety clamp 5 by adjusting a stroke of the second rod 12.
Optionally, the retainer ring 14 is provided with a notch along the radial direction, that is, the retainer ring 14 is a non-fully-enclosed ring body and can slide along the second rod body 12. The opening of the limit ring 14 is connected with a screw, and when the limit ring 14 moves to a designated position, the limit ring 14 can be fastened through the screw.
Referring to fig. 1, 2 and 3, as an optional technical scheme of this application, still slide on the second body of rod 12 and be provided with locating plate 6, locating plate 6 is used for fixed mounting at the top of container, and the upper end of spring 3 supports and presses at locating plate 6. The effect of locating plate 6 is mainly used for bearing the pressure that supports of spring 3, avoids the top direct contact of spring 3 and container, and secondly locating plate 6 also provides a plane, strengthens the flexible stability of spring 3.
Referring to fig. 4, the present embodiment further discloses a material lifting system, which includes the vertical steel frame 100, the container 200, and the braking device in any of the above embodiments.
The vertical steel frame 100 is a frame body with a square cross section formed by welding angle steel, and the container 200 is arranged in the vertical steel frame 100 in a sliding mode.
Referring to fig. 5 and 6, the sleeve 2 is positioned inside the container 200 near the top of the container 200, the link 4 is hinged inside the container 200, and the safety clamp 5 is fixedly mounted on the container 200. When the braking device is installed, the second rod 12 is inserted downward into the container 200, the sleeve 2 and the spring 3 are installed, and finally the connecting rod 4 and the safety clamp 5 are installed at both sides of the inside of the container 200.
The vertical direction of going up along being provided with guide rail 110 on the perpendicular steelframe 100, when arresting gear installed on container 200, two splint of safety clamp 5 distribute in the both sides of guide rail 110, and when safety clamp 5 moved, two splint can press from both sides tight guide rail 110.
