Detailed Description
A detailed description of an embodiment of the present invention is provided below with reference to fig. 1-5.
Examples
The embodiment is a gantry crane for safe climbing, and comprises two pillars 11, a beam 12 fixedly connected with the upper ends of the two pillars 11, and each bottom plate 13 fixedly connected with the lower end of the corresponding pillar 11. One of the two pillars 11 is provided with a plurality of climbing rods 111 from top to bottom, and one side of the pillar 11 provided with the climbing rods 111 is connected with a safety rod 2. The lower end of the safety rod 2 is fixedly connected with a corresponding bottom plate 13, and the upper end of the safety rod is fixedly connected with the cross beam 12 through a connecting rod. The safety rod 2 is connected with a locking mechanism 3 in a sliding mode, and the locking mechanism 3 is connected with a safety belt connected with a person. The locking mechanism 3 comprises a front plate 30 and a rear plate 31 which are spaced from each other in the front-rear direction, an upper plate 32 fixedly connected with the upper ends of the front plate 30 and the rear plate 31, a side plate 33 fixedly connected with the left ends of the front plate 30, the rear plate 31 and the upper plate 32, and a rotating rod 34 rotatably connected with the inner sides of the front plate 31 and the rear plate 31. The upper end of the upper plate 32 is provided with a through hole which is sleeved on the safety rod 2. The rotating rod 34 comprises a resisting block 341 and a control handle 342 fixedly connected with the resisting block 341, a rotating hole is arranged at the joint of the resisting block 341 and the control handle 342, a rotating shaft 311 rotatably connected with the rotating hole is arranged between the front plate 30 and the rear plate 31, and the rotating shaft 311 is fixedly connected with the front plate 31 and the rear plate 31. The abutting block 341 is located between the front and rear plates 31, and the lever 342 has a portion located between the front and rear plates 31 and another portion extending away from the side plate 33 in the direction of the climbing rod 111 and located outside the front and rear plates 31. The upper end of the lever 342 rests against the upper plate 32, in which position the abutment block 341 is not in contact with the safety bar 2. Use this locking mechanical system 3, fall downwards when the maintenance personal, will pull the downward one end in control handle 342 outer end, so control handle 342 will rotate around axis of rotation 311 with supporting piece 341, make supporting piece 341 and safety lever 2 conflict like this, make locking mechanical system 3 tightly clip safety lever 2, locking mechanical system 3 can not the downstream like this, so also pull the maintenance personal, make the maintenance personal can not continue to fall downwards, ensure that the maintenance personal can not be injured because of falling, the life safety of maintenance personal has been protected to a certain extent.
Further: the upper end of the upper plate 32 is connected with a sliding sleeve 35 at the through hole, the sliding sleeve 35 is sleeved on the safety rod 2, so that the sliding sleeve 35 plays a certain limiting role, one end of the locking mechanism 3 is guided, and the locking mechanism 3 can only slide along the length direction of the safety rod 2.
Further: one side of the safety lever 2 close to the abutting block 341 is provided with a first tooth portion 21 from top to bottom, and the first tooth portion 21 comprises a plurality of continuous teeth connected with the safety lever 2. The end of the abutment block 341 close to the safety lever 2 is provided with a second tooth 3411, the second tooth 3411 comprising several consecutive teeth connected to the end of the abutment block 341. When the first tooth portion 21 and the second tooth portion 3411 are abutted together, the abutting block 341 is abutted against the safety lever 2 more tightly, so that friction is increased, and the locking mechanism 3 cannot slide along the safety lever 2. A bracket 36 is connected to the upper end of the upper plate 32, a spring 37 is connected to the bracket 36, the lower end of the spring 37 is connected to the control handle 342, and in the absence of an external force (excluding the weight of the safety belt), the spring 37 steps on the rotating rod 34, so that the abutting block 341 does not contact the safety lever 2, and thus it is ensured that the locking mechanism 3 can slide up and down on the safety lever 2.
Further: the locking mechanism 3 is provided with a connecting lug 343, specifically, the connecting lug 343 is fixedly connected with one end of the control handle 342 far away from the safety rod 2, then the connecting lug 343 is connected with the safety belt, and the safety belt for working aloft is provided with a hook, so that the hook can be hooked on the connecting lug 343.
Further: the position fixedly connected with peg 121 that the crossbeam 12 upper end is close to safety lever 2 even has the string rope (not drawn in the picture) on the locking mechanical system 3, and string rope one end can be tied up on support 36, hangs the rope other end and ties into the ring, and when maintenance personal climbed crossbeam 12 like this, can be on peg 121 to the ring cover of hanging the rope, so pulling locking mechanical system 3 for after the safety belt left locking mechanical system 3, locking mechanical system 3 can not drop downwards, so in order to be equipped with maintenance personal to climb down pillar 11 and use.
Further: the bottom plate 13 connected with the safety rod 2 is fixedly connected with a supporting rod 131 at a position close to the safety rod 2, the upper end of the supporting rod 131 is fixedly connected with a supporting plate 132 used for placing a locking mechanism 3, therefore, when the locking mechanism 3 is not used, the locking mechanism 3 is supported by the supporting plate 132, so that the locking mechanism 3 is away from the ground by a certain distance, and when the height of the supporting rod 131 is set to be 0.8m-1.2 m, people use the locking mechanism 3 next time, the use is convenient, and the locking mechanism 3 does not need to be held up by bending down.
Further: the safety rod 2 is square, the through hole of the upper plate 32 is also square, and the square has a certain limiting function, so that the locking mechanism 3 cannot rotate around the safety rod 2, and thus, when a maintenance worker falls, the maintenance worker cannot be far away from the climbing rod 111 due to rotation, so that the maintenance worker can smoothly grasp and step on the climbing rod 111 again, and the maintenance worker can climb up or down the pillar 11 again.
The utility model only adds a climbing rod, a safety rod and a locking mechanism on the basis of the prior portal crane, so the structures are mainly explained, other prior parts of the crane are not design points, the description does not explain the prior parts for the sake of brief explanation, and the description is not drawn on the attached drawings.
The using method comprises the following steps: maintenance personal or other personnel wear the safety belt of high altitude construction, then the couple of safety belt colludes on the engaging lug, then climb to the pillar along the climbing pole, the control handle is upwards being drawn to the safety belt, then the control handle takes locking mechanism to move up along the safety lever, fall downwards when maintenance personnel, will draw the downward removal in control handle outer end, so the control handle with support the piece and will rotate around the axis of rotation, make to support tight piece and safety lever conflict like this, make locking mechanism clip the safety lever tightly, locking mechanism can not the downward movement like this, so just pull maintenance personnel, make maintenance personnel can not continue to fall downwards, ensure that maintenance personnel can not be injured because of falling, maintenance personnel's life safety has been protected to a certain extent. When the maintenance personal climbs downwards along the pillar and falls, the safety of the maintenance personal climbing up and down the pillar is guaranteed in the same way as the above.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art should be able to make general changes and substitutions within the technical scope of the present invention.
