Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to an auxiliary device for engineering measurement. Background Art

[0002] Engineering surveying is a general term for various surveying work carried out in the design, construction and management stages of engineering construction. Earthwork measurement is an important part of engineering construction, mainly used to determine the construction volume of excavation, landfill and other earthwork projects. In various engineering construction projects, earthwork volume calculation is a regular and indispensable task, and its accuracy directly affects the construction period and economic benefits. Therefore, earthwork measurement is an important part of engineering surveying and is of great significance to ensuring the smooth progress of engineering construction.

[0003] However, the earthwork thickness measuring ruler is manually pressed into the soil layer to be measured. During the manual operation, it cannot be guaranteed that the force applied to the measuring ruler is always perpendicular to the ground. If the measuring ruler is deflected, the measurement result will be biased.

[0004] The existing patent (Announcement No.: CN213714158U) is an auxiliary device for measuring earthwork for engineering cost. The first level and two sets of second level are used to observe whether the workbench is in a horizontal state. When the workbench is in a tilted state, the length of the telescopic rod is adjusted to make the workbench horizontal. The measuring tube is rotated by twisting the handle. The measuring tube is inserted into the ground together with the cone head. The scale value on the measuring ruler can be observed through the measuring tube to measure the thickness of the earthwork. The measuring ruler can be prevented from tilting and the measurement accuracy is high.

[0005] In view of the above problems, the existing patent provides a solution, but when adjusting the length of the telescopic rod, the user is required to manually rotate the limit bolt. After rotation, the user is required to hold the telescopic rod with one hand and then tighten the limit bolt. When tightening the limit bolt, the user's body will shake, causing the hand holding the telescopic rod to shake as well, affecting the adjustment of the length of the telescopic rod, and further affecting the measurement efficiency.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 6 , the utility model provides a technical solution:

[0031] An auxiliary device for engineering measurement, comprising a base plate 1, a measuring mechanism 2 for auxiliary measurement of earthwork is arranged inside the base plate 1, and a clamping component 3 for improving the accuracy of the measuring mechanism 2 is arranged inside the measuring mechanism 2;

[0032] The measuring mechanism 2 includes a screw barrel 201, a stainless steel screw rod 202, a support platform 203, a spirit level 204, a plastic screw rod 205, a measuring ruler 206 and a guide cone 207. The screw barrel 201 is rotatably connected to the bottom of the base plate 1, the stainless steel screw rod 202 is threadedly connected to the inside of the screw barrel 201, the support platform 203 is welded to the bottom of the stainless steel screw rod 202, the spirit level 204 is arranged on the top of the base plate 1, the plastic screw rod 205 is threadedly connected to the inside of the base plate 1, the measuring ruler 206 is arranged inside the plastic screw rod 205, and the guide cone 207 is fused to the bottom of the plastic screw rod 205.

[0033] Specifically, Figure 4 As shown, a plurality of connecting rods 4 are welded to the top of the plastic screw rod 205 , and a circular column 5 is welded to the top of the connecting rod 4 for facilitating the rotation of the plastic screw rod 205 .

[0034] Specifically, Figure 4 As shown, a plurality of fixing cones 6 for increasing the contact area between the supporting platform 203 and the ground are welded at the bottom of the supporting platform 203, and the fixing cones 6 are made of stainless steel.

[0035] Specifically, Figure 5 As shown, the outer wall of the screw barrel 201 is provided with a plurality of grooves 9 for facilitating the rotation of the screw barrel 201 , and the top of the plastic screw rod 205 is threadedly connected with a cover body for preventing the measuring ruler 206 from shaking.

[0036] Specifically, Figure 1 As shown, a handle 10 is bolted to the side wall of the base plate 1 for easy carrying of the base plate 1 .

[0037] When it is necessary to measure the earthwork, the user can move the device to a suitable position through the handle 10, and then place the base plate 1 on the ground. When the base plate 1 is tilted, the user first manually leveled the base plate 1 roughly, and then the user holds the screw barrel 201 with one hand and rotates the stainless steel screw rod 202 with the other hand to make the stainless steel screw rod 202 descend until the fixed cone 6 is inserted into the ground and then the support platform 203 contacts the ground. At this time, the user releases the screw barrel 201 and the stainless steel screw rod 202 with both hands. The user observes the level meter 204 to see whether the base plate 1 is level. If it is not level, the user can rotate the screw barrel 201 to fine-tune the level of the base plate 1 again until the base plate 1 is level. After the adjustment is completed, the user can rotate the plastic screw rod 205 through the connecting rod 4 and the circular column 5 to make the plastic screw rod 205 descend. Because the plastic screw rod 205 is made of transparent plastic material, the user can observe the descending depth of the measuring ruler 206 from the outside, thereby measuring the earthwork.

[0038] Specifically, Figure 6 As shown, the clamping assembly 3 includes a bidirectional screw rod 301, a clamping plate 302 and a straight groove 303. The bidirectional screw rod 301 is rotatably connected to the inside of the plastic screw rod 205, the clamping plate 302 is threadedly connected to the outside of the bidirectional screw rod 301, and the straight groove 303 is opened at one end of the bidirectional screw rod 301.

[0039] Specifically, Figure 6 As shown, a baffle 7 is welded inside the plastic screw 205 to prevent the measuring ruler 206 from contacting the bidirectional screw 301 . One end of the baffle 7 passes through the clamping plate 302 and is slidably connected to the clamping plate 302 .

[0040] Specifically, Figure 6 As shown, a protective pad 8 is bonded to the side wall of the clamping plate 302 to prevent the measuring ruler 206 from being damaged by clamping, and the protective pad 8 is made of rubber material.

[0041] Before the measuring ruler 206 descends, the user can use an external screwdriver to rotate the bidirectional screw rod 301 to move the two clamping plates 302 in opposite directions, thereby clamping the measuring ruler 206 to prevent the measuring ruler 206 from shaking when descending, thereby affecting the measurement result.

[0042] By adopting the above technical solution, the problem that the existing auxiliary device for engineering measurement requires the user to manually rotate the limit bolt when adjusting the length of the telescopic rod, and after rotation, the user needs to hold the telescopic rod with one hand and then tighten the limit bolt. When tightening the limit bolt, the user's body will shake, causing the hand holding the telescopic rod to shake, affecting the adjustment of the length of the telescopic rod, and further affecting the measurement efficiency is solved.

[0043] Working principle: Before measuring earthwork, the user rotates the bidirectional screw rod 301 with an external screwdriver to move the two clamping plates 302 in opposite directions, thereby clamping the measuring ruler 206 to prevent the measuring ruler 206 from shaking when it is lowered, thereby affecting the measurement result. When earthwork measurement is required, the user can move the device to a suitable position through the handle 10, and then place the base plate 1 on the ground. When the base plate 1 is tilted, the user first manually level the base plate 1 roughly, and then the user holds the screw barrel 201 with one hand and rotates the stainless steel screw rod 202 with the other hand to make the stainless steel screw rod 202 descend until the fixed cone 6 is inserted into the ground and then the support platform 203 contacts the ground. At this time, the user releases the screw barrel 201 and the stainless steel screw rod 202 with both hands. The user observes the level meter 204 to see whether the base plate 1 is level. If it is not level, the user can rotate the screw barrel 201 to fine-tune the level of the base plate 1 again until the base plate 1 is level. After the adjustment, the user can rotate the plastic screw rod 205 through the connecting rod 4 and the circular column 5 to make the plastic screw rod 205 descend. Because the plastic screw rod 205 is made of transparent plastic material, the user can observe the descending depth of the measuring ruler 206 from the outside to measure the earthwork.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
