Technical Field
[0001] The utility model belongs to the technical field of hand-held devices for trench closed covers, and particularly relates to a combined cover handle device. Background Technique
[0002] In sewage treatment plants and water supply plants, trench closed covers are mostly made of precast concrete. To facilitate the lifting and handling of the covers during trench maintenance, lifting steel bars are usually provided on the top of the covers.
[0003] After the trench is closed, the lifting steel bars on the top of the cover are directly exposed. The steel bars on the top of the cover will block pedestrians, affecting people's normal passage and making it inconvenient for people to use. In addition, during the lifting process, the staff directly holds the steel bars to lift the cover, with poor buffering performance, which affects the staff's lifting of the cover.
[0004] The above two problems are both manifested as poor buffering performance during the use of the handle device, affecting people's lifting of the cover, normal use, inconvenient removal of the handle device, and the exposed device affecting people's passage. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] As shown in Figures 1-6 , a reserved hole 1 is provided at the top of the prefabricated cover plate 2, a reserved bolt 3 is cast inside the prefabricated cover plate 2, the top of the reserved bolt 3 extends into the inner cavity of the reserved hole 1, a ring nut 4 is threadedly sleeved on the surface of the reserved bolt 3, a locking spring buckle 6 is sleeved on the surface of the ring nut 4, a pulling rope 5 is sleeved on the opposite side of the locking spring buckle 6, a buffer assembly 18 is provided on the opposite side of the pulling rope 5, and a cover plate ditch wall 8 is provided at the bottom of the prefabricated cover plate 2.
[0025] By providing the water permeable hole 7, the drain pipe 17 and the discharge hole, it is possible to facilitate the discharge of the accumulated water existing in the reserved hole 1, and effectively prevent the accumulation of water in the reserved hole 1. By providing the hole cover 9, it is possible to facilitate the closing of the reserved hole 1, effectively prevent dust and sundries from entering the reserved hole 1, and facilitate the installation of the ring nut 4 by screwing it on the surface of the reserved bolt 3.
[0026] As a preferred embodiment of the present utility model, as shown in Figure 1 and Figure 6 , this embodiment provides a high-stability hydraulic pliers, including a first mounting bracket 11. The opposite side of the pulling rope 5 is adhered to the first mounting bracket 11. A damper 12 is connected to the inner wall of the first mounting bracket 11 by bolts. A second mounting bracket 14 is connected to the surface of the damper 12 by bolts. A buffer spring 13 is sleeved on the surface of the damper 12. A connecting rope 15 is adhered to the opposite side of the second mounting bracket 14.
[0027] When the above-mentioned embodiments are implemented, that is, when it is necessary to lift the precast cover plate 2, the ring nut 4 is screwed onto the surface of the reserved bolt 3 for installation. Then, the locking spring buckle 6 is stuck inside the ring nut 4. One can hold the grip sleeve 16, and then drive the connecting rope 15, the second mounting bracket 14, the buffer spring 13, the damper 12, the first mounting bracket 11, and the lifting rope 5 by pulling the grip sleeve 16 to drive the locking spring buckle 6 to move up and down. The locking spring buckle 6 drives the reserved hole 1 and the ring nut 4 to move up and down to lift the reserved hole 1. When moving the reserved hole 1, the reserved hole 1 drives the ring nut 4, the lifting rope 5, and the locking spring buckle 6 to move up and down. The lifting rope 5 drives the first mounting bracket 11 to move up and down. The first mounting bracket 11 and the second mounting bracket 14 drive the buffer spring 13 to expand and contract, and the damper 12 performs damping movement for buffering.
[0028] In some embodiments, as Figure 2 shown, a rubber strip 10 is adhered to the bottom of the precast cover plate 2. The bottom of the rubber strip 10 contacts the groove wall 8 of the cover plate. A water-permeable hole 7 is provided on the front side of the precast cover plate 2. The rear side of the water-permeable hole 7 communicates with the hole cover 9. A discharge hole is provided on the front side of the groove wall 8 of the cover plate. A drain pipe 17 is communicated with the front side of the groove wall 8 of the cover plate. The rear side of the drain pipe 17 communicates with the discharge hole. A hole cover 9 is provided on the top of the precast cover plate 2. The bottom of the hole cover 9 is inserted into the reserved hole 1.
[0029] This embodiment is to facilitate the insertion of the hole cover 9 into the reserved hole 1 during operation to close the reserved hole 1 and prevent sundries from entering the reserved hole 1. When there is accumulated water inside the reserved hole 1, the accumulated water in the reserved hole 1 can be discharged through the water-permeable hole 7, the discharge hole, and the drain pipe 17, preventing the reserved bolt 3 from being damaged due to long-term soaking in water. When the precast cover plate 2 is snapped into the groove wall 8 of the cover plate, the rubber strip 10 can seal the connection between the precast cover plate 2 and the groove wall 8 of the cover plate, effectively preventing sundries from entering the groove wall 8 of the cover plate.
[0030] In use, after covering the top of the cover ditch wall 8 with the precast cover plate 2, when it is not necessary to lift the precast cover plate 2, cover the hole cover 9 on the top of the reserved hole 1 to seal the top of the reserved hole 1. When it is necessary to lift the precast cover plate 2 for maintenance, remove the hole cover 9 from the top of the reserved hole 1, then screw the eyebolt nut 4 onto the surface of the reserved bolt 3, then snap the lock spring buckle 6 into the eyebolt nut 4, and then hold the grip sleeve 16. Then, by pulling the grip sleeve 16, drive the connecting rope 15, the second mounting bracket 14, the buffer spring 13, the damper 12, the first mounting bracket 11 and the lifting rope 5 to drive the lock spring buckle 6 to move up and down. Drive the reserved hole 1 to move up and down by driving the reserved hole 1 and the eyebolt nut 4 to move up and down through the lock spring buckle 6. When moving the reserved hole 1, the reserved hole 1 will drive the eyebolt nut 4, the lifting rope 5 and the lock spring buckle 6 to move up and down. Drive the first mounting bracket 11 to move up and down through the lifting rope 5, drive the buffer spring 13 to do telescopic movement through the first mounting bracket 11 and the second mounting bracket 14, and perform damping movement through the damper 12 for buffering.
