Ground leveling system

Abstract

The present invention provides a ground leveling system, which includes: a leveling mechanism and a level control mechanism. The ground leveling system of the present invention adopts the principle of liquid communication vessels, and the liquid level height of the water level gauge of the system is almost not affected by the distance from the mother liquid in the transparent water bucket. Since the liquid surface area of ​​the transparent water bucket is hundreds of times larger than the liquid surface area in the water level gauge, when the system works at a normal speed, no matter how the water level gauge fluctuates, the liquid level height change amplitude in the transparent water bucket is only a few hundredths of the change amplitude of the water level gauge, and the error is almost negligible. The stable liquid level of the transparent water bucket will firmly lock the liquid level in the water level gauge of the horizontal leveling machine, and the construction accuracy will always be stable within the set range at a normal construction speed, fully ensuring the leveling requirements during the construction process.

Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a ground leveling system. Background Art

[0002] At present, the pouring of floor slabs and floor heating cushion layers are all done by manually measuring with wires in advance, arranging cement cakes on the ground to set elevation points, to locate the pouring thickness, and then using a ruler to scrape it flat, and manually patting it to finish it. This is not only inefficient and difficult to ensure quality, but also often results in hollow drums and rework, resulting in a waste of manpower and material resources. Due to the lack of a laser leveling machine that can walk on cast-in-place steel bar formwork, the cast-in-place formwork of the floor top slab is manually leveled with a ruler, and then manually or with a trowel to finish it. The entire cast-in-place surface has a large error, and usually a 3-5 cm height needs to be reserved for the subsequent secondary floor pouring and leveling, which also results in a huge waste of manpower and material resources. Therefore, it is necessary to propose further solutions to the above problems. Summary of the invention

Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0019] The present invention is described in detail below in conjunction with various embodiments, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0020] like Figure 1 As shown, a ground leveling system according to an embodiment of the present invention includes: a leveling mechanism 1 and a levelness control mechanism 2 .

[0021] The leveling mechanism 1 comprises: a leveling ruler 11 , a scraper 12 , a fixing bracket 13 , a lifting structure 14 and a manipulation structure 15 .

[0022] The vibrating ruler 11 is used to break up the castable material that needs to be leveled by vibration, so as to level the castable material. Specifically, the vibrating ruler 11 has a vibrating surface that can contact the castable material, and the vibrating ruler 11 is horizontally arranged and connected to the bottom of the fixed bracket 13. In order to make the vibrating ruler 11 vibrate, a motor 16 is arranged on the vibrating ruler 11 to drive it to vibrate. Correspondingly, at least one battery 17 for powering the motor 16 is also arranged on the fixed bracket 13.

[0023] The scraper 12 is used to disperse and flatten the castable. Specifically, the scraper 12 is located on one side of the vibrating ruler 11 and is connected to the fixed bracket 13 through a lifting structure 14. In one embodiment, the scraper 12 is vertically arranged, and its lower end edge has an inclined angle and is aligned with the working surface of the vibrating ruler 11. In this way, the dual effects of the vibrating ruler 11 and the scraper 12 are conducive to uniformly leveling the castable. The lifting structure 14 is used to drive the scraper 12 to rise and fall, so as to control the scraper 12 within the set leveling accuracy. In one embodiment, the lifting structure 14 is located in a vertically arranged push cylinder.

[0024] The control structure 15 is used to control the leveling movement of the vibrating ruler 11 and the scraper 12. Specifically, one end of the control structure 15 is a handheld end, and the other end is pivotally connected to the fixed bracket 13. In one embodiment, the control structure 15 includes a connecting rod 151, one end of the connecting rod 151 is pivotally connected to the middle position of the fixed bracket 13, and the other end is provided with handles 152 suitable for holding. In this way, through the above-mentioned control structure 15, the construction personnel can maintain a standing posture to carry out the leveling construction, which is convenient for the construction personnel to operate.

[0025] The fixing bracket 13 is used to fix the vibrating ruler 11 and the scraper 12. Specifically, the fixing bracket 13 includes: oppositely arranged vertical plates, a crossbar connected between the vertical plates, and the vertical plates on either side are connected to the scraper 12 through the lifting structure 14. In addition, a handle is provided on the outer side of each vertical plate.

[0026] The level control mechanism 2 is used to adjust the level of the leveling mechanism 1 in real time, so that the construction accuracy of the leveling mechanism 1 will always be stable within the set range, fully ensuring the leveling requirements during the construction process.

[0027] Specifically, the level control mechanism 2 includes: a transparent water bucket 21, a conduit 22, a water level gauge 23, an upper inductive proximity switch 24, and a lower inductive proximity switch 25. The water level gauge 23 is connected to the upper edge of the scraper 12, and the upper inductive proximity switch 24 is arranged at the upper end of the water level gauge 23, and the lower inductive proximity switch 25 is arranged at the lower end of the water level gauge 23. The water level gauge 23 is connected to the transparent water bucket 21 through the conduit 22, and the upper inductive proximity switch 24 and the lower inductive proximity switch 25 transmit signals to the lifting structure 14. Further, there are two water level gauges 23, and the water level gauges 23 are respectively arranged at the two ends of the scraper 12. In this way, the level of both ends of the scraper 12 can be accurately adjusted.

[0028] The level control mechanism 2 of this embodiment is based on the principle of communicating vessels in which the same liquid has the same liquid level in two connected containers. Water or other liquid is injected into the transparent water bucket 21, and the height of the transparent water bucket 21 is adjusted to set the liquid level in the bucket to a required height as a reference height for leveling construction. At this time, the liquid level of the water level gauge 23 connected to the water bucket through the conduit 22 will be forced to be the same as the liquid level in the transparent water bucket 21. The construction accuracy of the vibrating ruler 11 and the scraper 12 can be set by adjusting the distance between the upper and lower inductive proximity switches of the water level gauge 23.

[0029] During construction, the transparent water bucket 21 is placed still on the ground. When the system starts to move and level, the water level gauge 23 fixed on the scraper 12 will rise and fall with the scraper 12, and the liquid level in the water level gauge 23 will rise or fall with the rise and fall of the water level gauge 23 to maintain the same height as the mother liquid in the transparent water bucket 21. When the liquid level in the water level gauge 23 fluctuates up and down to the inductive proximity switch, the inductive proximity switch will be automatically triggered and transmit the signal to the push cylinder to drive the scraper 12 to rise or fall, always controlling the entire scraper 12 within the set leveling accuracy.

[0030] In addition, the level control mechanism 2 further includes an adjustment bracket 26, and the transparent water bucket 21 is mounted on the adjustment bracket 26. The adjustment bracket 26 includes: a bracket seat 261, a plurality of inclined rods 262 pivotally connected to the bracket seat 261, and a lifting rod 263 connected to the bottom of the bracket seat 262.

[0031] To sum up, the ground leveling system of the present invention adopts the principle of liquid communication vessels. The liquid level of the water level gauge of the system is almost not affected by the distance from the mother liquid in the transparent water bucket. Since the liquid surface area of ​​the transparent water bucket is hundreds of times larger than the liquid surface area in the water level gauge, when the system is working at normal speed, no matter how the water level gauge fluctuates, the change amplitude of the liquid level in the transparent water bucket is only a few hundredths of the change amplitude of the water level gauge, and the error is almost negligible. The stable liquid level in the transparent water bucket will firmly lock the liquid level in the water level gauge of the horizontal leveling machine. The construction accuracy at normal construction speed will always be stable within the set range, fully ensuring the leveling requirements during construction.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
