Description

Technical Field

[0001] The utility model relates to a novel hydraulic surveying benchmark, belonging to the field of engineering surveying. Background Art

[0002] In the construction of water conservancy projects, measuring poles are often used. Usually one person holds the pole while another person surveys the pole. A pointed head is installed at the bottom of the measuring pole so that the pointed head is inserted into the ground to limit the position of the measuring pole. After the measurement work at a certain point on the ground is completed, the pointed head needs to be separated from the ground. In order to reduce the resistance to pulling out the pointed head, before pulling out the pointed head, personnel usually use the method of reciprocating shaking the measuring pole to create a gap between the pointed head and the ground. The problem with this method is that the reaction force received by the pointed head when squeezing the ground will act on the measuring pole. Therefore, the strength requirements of the measuring pole are relatively high, and the production cost of the measuring pole increases accordingly. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a new type of hydraulic measuring pole to solve the problems raised in the above-mentioned background technology. The utility model reduces the requirements for the strength of the measuring pole and plays a role in protecting the measuring pole.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a new type of water conservancy measuring benchmark, including a measuring benchmark, the outer surface of the measuring benchmark is processed with scale lines from top to bottom, a detachable chassis is installed at the lower end of the measuring benchmark, a pointed head is installed at the middle position of the bottom of the chassis, a plug-in sleeve is installed on the upper surface of the chassis, the plug-in sleeve is arranged on the side of the measuring benchmark away from the scale lines, a plug-in rod is inserted in the plug-in sleeve, the upper end of the plug-in rod is sleeved with a hollow tube, the outer surface of the lower end of the hollow tube is threadedly connected with a positioning screw for limiting the relative position of the plug-in rod and the hollow tube, the upper end of the hollow tube is connected and fixed with a bent pipe, the end of the bent pipe away from the hollow pipe is connected and fixed with a reducer, and the end of the reducer away from the bent pipe is installed with a handle.

[0005] Furthermore, a straight threaded barrel which is staggered with the plug sleeve is connected and fixed to the middle position of the upper surface of the chassis, and an external thread is processed on the outer surface of the lower end of the measuring benchmark, and one end of the measuring benchmark with the external thread is threadedly connected in the straight threaded barrel.

[0006] Furthermore, a connecting plate is connected and fixed to the outer surface of the straight threaded barrel, and one end of the connecting plate away from the straight threaded barrel is connected and fixed to the plug sleeve.

[0007] Furthermore, the cross section of the plug sleeve is rectangular, the cross section of the plug rod is rectangular, and the cross section of the hollow tube is rectangular.

[0008] Further, an internally threaded sleeve communicating with the hollow tube is fixedly connected to the outer surface of the lower end of the hollow tube. One end of the positioning screw is threadedly connected inside the internally threaded sleeve, and a knob head is installed at the end of the positioning screw outside the internally threaded sleeve.

[0009] Further, a threaded head is fixedly connected to the middle position of the surface of the pointed head close to the chassis. A threaded hole is opened at the middle position of the bottom of the chassis. The threaded head is threadedly connected in the threaded hole. A pin hole for inserting an extension rod is opened on the outer surface of the end of the pointed head close to the threaded head, and the pin hole penetrates through the pointed head.

[0010] Further, a rubber sleeve is sleeved on the handle, and both ends of the rubber sleeve are open.

[0011] Advantages of the present utility model:

[0012] 1. Insert the insertion rod into the insertion sleeve to realize the insertion of the insertion rod and the base.

Subsequently, use the positioning screw to limit the relative position of the hollow tube and the insertion rod, which is convenient for adjusting the height of the handle according to personal height and meets the use needs of people with different heights.

[0013] 2. Under the action of the bent tube, there is enough space for a person's hand to grasp the handle between the handle and the measuring benchmark. Shake the chassis reciprocally with the structure formed by components such as the handle, the bent tube, the hollow tube, the insertion rod, and the insertion sleeve. The chassis drives the pointed head to shake reciprocally in the ground, creating a gap between the pointed head and the ground, which is convenient for reducing the resistance to pulling out the pointed head from the ground. Since the reaction force received by the pointed head pressing on the ground does not directly act on the measuring benchmark, the requirement for the strength of the measuring benchmark is reduced, playing a role in protecting the measuring benchmark and being beneficial to reducing the production cost of the measuring benchmark.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figure 1 and Figure 2 The present utility model provides a technical solution: a new type of water conservancy measuring rod, including a measuring rod 1. Scale lines 14 are processed on the outer surface of the measuring rod 1 from top to bottom. A detachable chassis 3 is installed at the lower end of the measuring rod 1. Among them, a straight thread cylinder 2 misaligned with the socket sleeve 6 is fixedly connected to the middle position of the upper surface of the chassis 3. External threads are processed on the outer surface of the lower end of the measuring rod 1, so that the threaded end of the measuring rod 1 processed with external threads is threadedly connected into the straight thread cylinder 2, realizing the assembly of the measuring rod 1 and the chassis 3.

[0022] Refer to Figures 1 - 4 In, a pointed tip 4 is installed at the middle position of the bottom of the chassis 3. Among them, a thread head 16 is fixedly connected to the middle position of the side of the pointed tip 4 close to the chassis 3. A threaded hole is opened at the middle position of the bottom of the chassis 3, so that the thread head 16 is threadedly connected into the threaded hole, completing the assembly of the pointed tip 4 and the chassis 3. A pin hole for inserting an extension rod is opened on the outer surface of the end of the pointed tip 4 close to the thread head 16, and the pin hole penetrates through the pointed tip 4, so that one end of the extension rod is inserted into the pin hole, facilitating the use of the extension rod to turn the pointed tip 4. When the head of the pointed tip 4 is severely worn, the thread head 16 is disengaged from the threaded hole, facilitating the separate replacement of the pointed tip 4.

[0023] Refer to Figure 1 and Figure 2, a socket sleeve 6 with a rectangular cross-section is installed on the upper surface of the chassis 3. The socket sleeve 6 is arranged on the side of the measuring benchmark 1 away from the scale line 14. A plug rod 7 with a rectangular cross-section is inserted into the socket sleeve 6. A hollow tube 9 with a rectangular cross-section is sleeved on the upper end of the plug rod 7. A positioning screw 8 for restricting the relative position between the plug rod 7 and the hollow tube 9 is threadedly connected to the outer surface of the lower end of the hollow tube 9. Wherein, a female screw sleeve 15 communicated with the hollow tube 9 is fixedly connected to the outer surface of the lower end of the hollow tube 9, so that one end of the positioning screw 8 is threadedly connected into the female screw sleeve 15, realizing the stable connection between the positioning screw 8 and the hollow tube 9. A knob head is installed at one end of the positioning screw 8 outside the female screw sleeve 15, which is convenient for screwing the positioning screw 8. The upper end of the hollow tube 9 is fixedly connected with a bent tube 10. One end of the bent tube 10 away from the hollow tube 9 is fixedly connected with a reducing pipe 11. A handle 12 is installed at one end of the reducing pipe 11 away from the bent tube 10. Under the action of the bent tube 10, there is enough space for a person's hand to grasp the handle 12 between the handle 12 and the measuring benchmark 1. A rubber sleeve 13 is sleeved on the handle 12. Both ends of the rubber sleeve 13 are open. The rubber sleeve 13 improves the comfort of grasping the handle 12. Insert the plug rod 7 into the socket sleeve 6 to realize the insertion connection between the plug rod 7 and the base. Adjust the length of the plug rod 7 inserted into the hollow tube 9 until the position of the handle 12 meets the individual needs. Subsequently, use the positioning screw 8 to restrict the relative position between the hollow tube 9 and the plug rod 7, which is convenient for adjusting the height of the handle 12 according to the individual's height and meeting the use needs of people with different heights. Shake the chassis 3 reciprocally with the structure formed by components such as the handle 12, the bent tube 10, the hollow tube 9, the plug rod 7 and the socket sleeve 6. The chassis 3 drives the pointed head 4 to shake reciprocally in the ground, so that a gap is generated between the pointed head 4 and the ground, which is convenient for reducing the resistance of pulling out the pointed head 4 from the ground. Since the reaction force received by the pointed head 4 pressing the ground does not directly act on the measuring benchmark 1, the requirement for the strength of the measuring benchmark 1 is reduced, playing a role in protecting the measuring benchmark 1 and being beneficial to reducing the production cost of the measuring benchmark 1.

[0024] Refer to Figure 1 and Figure 2 , a connecting plate 5 is fixedly connected to the outer surface of the straight thread cylinder 2. One end of the connecting plate 5 away from the straight thread cylinder 2 is fixedly connected to the socket sleeve 6. Under the action of the connecting plate 5, the stability of the installation of the straight thread cylinder 2 and the socket sleeve 6 is improved.
