Description

Technical Field

[0001] The utility model relates to the field of surveying and measuring instruments, in particular to a surveying and measuring instrument for a construction site. Background Art

[0002] Surveying and mapping refers to the measurement, collection and mapping of the shape, size, spatial position and attributes of natural geographical elements or artificial facilities on the surface, which provides a control basis for topographic maps and a basis for various engineering constructions. Some specific measuring instruments are used in the process of surveying and mapping.

[0003] In the prior art, a utility model patent with publication number CN 218097762 U proposes a mapping measuring device for construction sites. By setting a folding assembly, a push rod can be divided into two, which is convenient for personnel to fold and carry the device. Through the function of the support assembly, when personnel need to record data, the support assembly can be put down so that the legs are in contact with the ground, and the device can be placed on the ground, which is convenient for personnel to pick up and use again. The operation is simple and convenient, which can improve the work efficiency of the staff.

[0004] However, its single-wheel structure design cannot maintain a straight walking path of the device when in use, nor does it have the ability to mark the walking path. It is prone to swinging when measuring on site, which leads to a certain amount of deviation in the measurement results, affecting the construction progress and quality. Therefore, we need to upgrade and transform the existing technology to overcome its existing problems and shortcomings. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown in Figure 4, the present embodiment provides a surveying and measuring device for a construction site, including a device body 1, which contains a counter 2, a marking assembly 5 and a cover assembly 6. A handrail 3 is obliquely arranged at the rear end of the counter 2, and moving wheels 4 are transmission-connected on both sides of the counter 2. The marking assembly 5 is installed at the front center of the counter 2, the cover assembly 6 is arranged at the upper end of the counter 2, and a plug-in hole 21 is provided on the upper side wall of the counter 2.

[0025] Preferably, the marking assembly 5 includes a mounting seat 51, a guide slot 52 is provided at the front end of the mounting seat 51, and a slide bar 53 is provided in the guide slot 52, a limit ring 54 and a lower sleeve 55 are provided at the upper and lower ends of the slide bar 53, respectively, a clamping plate 56 is provided inside the lower sleeve 55, a movable shaft 57 is connected to the outer end of the clamping plate 56, and a first spring 59 is provided on the outer side of the movable shaft 57, the mounting seat 51 is fixed to the front end of the counter 2, the slide bar 53 slides up and down and is located in the guide slot 52, the limit ring 54 and the lower sleeve 55 are larger in diameter than the slide bar 53 and the guide slot 52, the clamping plate 56 is set to an arc structure and is movably located in the lower sleeve 55, the movable shaft 57 penetrates to the outer end of the lower sleeve 55 and is connected to an anti-slip pull rod 58, and the first spring 59 is movably sleeved on the movable shaft 57;

[0026] The marker pen or chalk can be inserted into the lower sleeve 55, and then the first spring 59 elastically pushes the clamping plate 56 to move and clamp it, so that it is stable in the lower sleeve 55 and the lower end is against the ground, which makes it convenient to mark the walking path. The slide rod 53 and the guide groove 52 cooperate to automatically drive the lower sleeve 55 down and make the chalk or marker pen always in contact with the ground, thereby maintaining the stability of the line marking.

[0027] Preferably, the cover assembly 6 includes an upper cover 61, a movable groove 62 is opened at the front end of the upper cover 61, a second spring 63 is arranged in the movable groove 62, the outer end of the second spring 63 is connected to the plug shaft 64, the upper cover 61 is hinged at the upper end of the counter 2, the outer end of the plug shaft 64 passes through the outer side of the movable groove 62 and corresponds to the plug hole 21, and a push-pull block 65 is fixedly connected to one side of the plug shaft 64;

[0028] The push-pull block 65 cooperates with the second spring 63 to control the plug-in shaft 64 to perform elastic telescopic movement, and the plug-in shaft 64 cooperates with the plug-in hole 21 to quickly open, close and fix the upper cover 61, which is convenient for inspection and maintenance of the counter 2.

[0029] The use principle and use process of the utility model are as follows: when using, first place the device at the starting point of the position to be detected, and then pull the movable shaft 57 and the clamping plate 56 to contract through the anti-slip pull rod 58, and the clamping plate 56 squeezes the first spring 59 to contract. At this time, the chalk or marker is inserted into the lower sleeve 55, and then the anti-slip pull rod 58 is released. The first spring 59 drives the clamping plate 56 to elastically reset and squeeze the chalk or marker to limit the position, and finally makes the end of the chalk or marker contact the ground. At this time, the handrail rod 3 is used to push the counter 2 and the moving wheel 4 to move in a straight line along the measuring path. The verticality of the walking path is judged by drawing lines with chalk or markers to ensure the accuracy of the measurement results. When the counter 2 needs to be adjusted or repaired, the two sets of push-pull blocks 65 can be squeezed inwardly, and the push-pull blocks 65 drive the plug-in shaft 64 and the second spring 63 to contract and disengage from the plug-in hole 21. At this time, the upper cover 61 can be opened, and then the counter 2 can be repaired and maintained, otherwise it can be covered again.
