Description

Technical Field

[0001] The present application relates to the field of hydrological observation, and particularly relates to an auxiliary pulley for wire laying of a ground hydrological observation hole. Background Art

[0002] The ground hydrological observation hole is an important facility for monitoring the groundwater level and water quality, which records the change of the groundwater level in real time and provides data support for water resource management. The cable in the auxiliary pulley for wire laying drives the measuring equipment of the observation hole to move, guiding the measuring equipment into the ground for measurement.

[0003] When some existing auxiliary pulleys for wire laying are in use, the downward movement of the cable will pull the entire pulley, without reducing the force on the pulley. After long-term use of the pulley, it is easy to cause damage to the pulley. And sometimes the pulley is also subject to accidental impact force, which may also cause damage to the pulley. Moreover, when using the pulley to lay wire, when one end of the cable reaches the designated position, the pulley body on the pulley is still rotating, and the pulley body cannot be fixed, reducing the practicability of the pulley. Summary of the Utility Model

[0004] An auxiliary pulley for wire laying of a ground hydrological observation hole provided by the present application can reduce a part of the force on the pulley when using the auxiliary pulley for wire laying, improve the service life of the pulley, and can fix the pulley body at the required position when using the pulley to lay wire, improving the practicability of the pulley.

[0005] In order to achieve the above object, the present application adopts the following technical solution: An auxiliary pulley for wire laying of a ground hydrological observation hole, the pulley comprising:

[0006] A base;

[0007] A boss, fixedly arranged on one side of the base, and two first connecting shafts are fixedly arranged on the inner wall of the boss;

[0008] Two transmission rods are respectively movably sleeved on the outer surfaces of the two first connecting shafts, and a second connecting shaft is movably embedded on one side of each of the two transmission rods. The two transmission rods can rotate with the two first connecting shafts or the two second connecting shafts as axes;

[0009] Two sliding cylinders are respectively fixedly arranged at both ends of the two second connecting shafts, and a cross bar is movably embedded in the inner walls of the two sliding cylinders. The two sliding cylinders can slide on the outer surfaces of the two cross bars;

[0010] A connecting plate is fixedly arranged at both ends of the cross bar, and two round rods are movably embedded on one side of the connecting plate. The two round rods can slide on one side of the connecting plate;

[0011] The support plate is fixedly arranged at one end of the two round rods, and a hook is fixedly arranged on one side of the support plate. The whole pulley is hung at the use location through the hook.

[0012] As a further improvement of the present application: on the opposite sides of the two sliding cylinders, first springs are fixedly arranged. The two first springs are movably sleeved on the outer surface of the cross bar. The two first springs can slide on the outer surface of the cross bar. When the two first springs are compressed, they will generate a reverse force, which will reduce part of the force received by the pulley.

[0013] As a further improvement of the present application: at one end of each of the two round rods, a baffle is fixedly arranged. The outer surfaces of the two round rods are movably sleeved with second springs. When the two second springs are compressed, they will generate a reverse force, reducing part of the force received by the pulley and protecting the whole pulley. When pressure is applied above the pulley, the two second springs will be compressed.

[0014] As a further improvement of the present application: a support rod is movably embedded on one side of the base. The outer surface of the support rod is movably sleeved with a pulley body. A fixing ring is fixedly arranged on one side of the pulley body. A plurality of notches are formed on the outer surface of the fixing ring. When paying out the wire, the pulley body can roll on the outer surface of the support rod.

[0015] As a further improvement of the present application: a sliding plate is slidably arranged on one side of the base. A pressing plate is fixedly arranged on one side of the sliding plate. The sliding plate can slide on one side of the base.

[0016] As a further improvement of the present application: a bottom plate is fixedly arranged on one side of the base. A sleeve is fixedly embedded on one side of the bottom plate. A threaded rod is threadedly embedded in the inner wall of the sleeve. One end of the threaded rod is movably arranged on one side of the sliding plate. When the cable reaches an appropriate distance, by rotating the turntable clockwise to drive the threaded rod to rotate, further driving one end of the threaded rod to drive the sliding plate to move downward, and further driving the pressing plate to drive the limiting block to move, so that the limiting block is stuck inside any one of the notches.

[0017] As a further improvement of the present application: a turntable is fixedly arranged at one end of the threaded rod. The turntable facilitates the rotation of the threaded rod. Rotating the turntable drives the threaded rod to rotate.

[0018] As a further improvement of the present application: a limiting block is fixedly arranged on one side of the pressing plate. The limiting block is matched with any one of the notches. The limiting block is stuck inside any one of the notches, further fixing the position of the fixing ring.

[0019] Compared with the prior art, the advantages and positive effects of the present application are that

[0020] The two second springs will also generate a reverse force when being squeezed, thereby reducing a part of the force received by the pulley and protecting the pulley. Therefore, when the line-releasing auxiliary pulley is used, a part of the force received by the pulley can be reduced, and the service life of the pulley can be improved.

[0021] 2. In the present application, when releasing the line, the pulley body can roll on the outer surface of the support rod. When the cable reaches a suitable distance, the threaded rod is driven to rotate by turning the turntable clockwise, and the slide plate can slide on one side of the base, further making one end of the threaded rod drive the slide plate to move downward, further making the pressure plate drive the limit block to move, so that the limit block is stuck inside any one of the slots, further fixing the position of the fixing ring, making the pulley body unable to roll, so that when using the pulley to release the line, the pulley body can be fixed to the required position, thereby improving the practicability of the pulley.

[0030] Embodiment 1, as Figures 1 to 5 shown, the present application provides a ground hydrographic observation hole alignment auxiliary pulley, and the pulley includes:

[0031] Base 1;

The two slide cylinders 204 can slide on the outer surfaces of the two cross bars 205;

[0035] Connecting plate 207, fixedly arranged at both ends of the cross bar 205, and two round rods 208 are movably embedded on one side of the connecting plate 207. The two round rods 208 can slide on one side of the connecting plate 207;

[0036] The support plate 209 is fixedly arranged at one end of two round rods 208, and a hook 212 is fixedly arranged on one side of the support plate 209. The whole pulley is hung at the usage location through the hook 212.

[0037] As Figures 1 to 5 shown, first springs 206 are fixedly arranged on the opposite sides of two sliding cylinders 204. The two first springs 206 are movably sleeved on the outer surface of the cross bar 205. The two first springs 206 can slide on the outer surface of the cross bar 205. When the two first springs 206 are squeezed, a reverse acting force will be generated, which will reduce part of the force received by the pulley.

[0038] As Figures 1 to 5 shown, baffles 211 are fixedly arranged at one end of two round rods 208. Second springs 210 are movably sleeved on the outer surfaces of the two round rods 208. When the two second springs 210 are squeezed, a reverse acting force will be generated to reduce part of the force received by the pulley and protect the whole pulley. When pressure is applied above the pulley, the two second springs 210 will be squeezed.

[0039] As Figures 1 to 5 shown, a support rod 3 is movably embedded on one side of the base 1. A pulley body 301 is movably sleeved on the outer surface of the support rod 3. A fixing ring 302 is fixedly arranged on one side of the pulley body 301. A plurality of notches 303 are formed on the outer surface of the fixing ring 302. When paying out the wire, the pulley body 301 can roll on the outer surface of the support rod 3.

[0040] As Figures 1 to 5 shown, a sliding plate 304 is slidably arranged on one side of the base 1. A pressing plate 309 is fixedly arranged on one side of the sliding plate 304. The sliding plate 304 can slide on one side of the base 1.

[0041] As Figures 1 to 5 shown, a bottom plate 305 is fixedly arranged on one side of the base 1. A sleeve 306 is fixedly embedded on one side of the bottom plate 305. A threaded rod 307 is threadedly embedded in the inner wall of the sleeve 306. One end of the threaded rod 307 is movably arranged on one side of the sliding plate 304. When the cable reaches the appropriate distance, by rotating the turntable 308 clockwise to drive the threaded rod 307 to rotate, further making one end of the threaded rod 307 drive the sliding plate 304 to move downward, and further making the pressing plate 309 drive the limiting block 310 to move, so that the limiting block 310 is stuck inside any one of the notches 303.

[0042] As Figures 1 to 5 shown, a turntable 308 is fixedly arranged at one end of the threaded rod 307. The turntable 308 facilitates the rotation of the threaded rod 307. Rotating the turntable 308 drives the threaded rod 307 to rotate.

[0043] As Figures 1 to 5As shown, a limit block 310 is fixedly provided on one side of the pressure plate 309 , and the limit block 310 matches with any one of the slots 303 . The limit block 310 is stuck inside any one of the slots 303 , further fixing the position of the fixing ring 302 .

[0044] Working principle: When using the auxiliary pulley for releasing the line, the entire pulley is hung at the place of use by the hook 212. When releasing the line, a cable is provided on the outer surface of the pulley body 301, and one end of the cable drives the measuring device to move downward. At this time, the entire pulley is subjected to a downward force, and the two transmission rods 202 can rotate with the two first connecting shafts 201 or the two second connecting shafts 203 as axes, respectively. The two slide cylinders 204 can slide on the outer surfaces of the two cross bars 205. At this time, the base 1 pulls the boss 2 downward, further causing the two transmission rods 202 to push the two slide cylinders 204, so that the two slide cylinders 204 and the connecting plate 207 squeeze the two first springs 206. When the two first springs 206 are squeezed, a reverse force will be generated, which will reduce a part of the force on the pulley. The two round rods 208 can slide on one side of the connecting plate 207. When the support plate 209 is subjected to force, the support plate 209 moves downward, further squeezing the support plate 209. The two second springs 210 are pressed, and the two second springs 210 will also generate a reverse force when being squeezed, thereby reducing a part of the force on the pulley and protecting the pulley. Therefore, when using the auxiliary pulley for line release, a part of the force on the pulley can be reduced, thereby increasing the service life of the pulley. When releasing the line, the pulley body 301 can roll on the outer surface of the support rod 3. When the cable reaches a suitable distance, the threaded rod 307 is driven to rotate by rotating the turntable 308 clockwise, and the slide plate 304 can slide on one side of the base 1, further making one end of the threaded rod 307 drive the slide plate 304 to move downward, further making the pressure plate 309 drive the limit block 310 to move, so that the limit block 310 is stuck in any one of the slots 303, further fixing the position of the fixing ring 302, making the pulley body 301 unable to roll, thereby when using the pulley for line release, the pulley body 301 can be fixed to the required position, thereby improving the practicality of the pulley.
