Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a plumb line device for construction engineering. Background Art

[0002] A plumb bob, also known as a plumb bob, refers to a conical object made of metal (iron, steel, copper, etc.). Currently, in construction projects, a plumb bob device is needed to measure the verticality of the object to ensure construction quality.

[0003] The currently used plumb bob device mainly consists of a housing, a connecting rope, and a plumb bob. The connecting rope is wrapped around the housing. When in use, the housing needs to be fixed at a high place, usually by pressing it with bricks or tying it at a high height with the connecting rope. The plumb bob then drops down. After use, the connecting rope is wrapped around the housing. However, the connecting rope is very easy to fall apart, causing it to become tangled and affecting the next use. The current method of winding the connecting rope using a motor-driven winding roller is heavy, and the lack of connection between the plumb bob and the housing can cause the plumb bob to pull out the connecting rope, making it inconvenient to store. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a plumb line device for construction engineering that can stably store plumb lines, facilitate the winding of connecting ropes, and is easy to use.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A plumb line device for construction engineering, comprising a housing, a connecting rope and a plumb line structure;

[0007] The housing has a receiving cavity, a housing cover is fixed to the housing by screws, two supports are fixed in the housing, a winding roller is rotatably mounted between the supports, one end of the winding roller passes through the support and is fixedly connected to the output shaft of the servo motor, the servo motor is fixedly mounted in the housing, a receiving portion is formed concavely on the housing, a wire hole is provided through the receiving portion, and one end of the connecting rope is fixedly connected to the winding roller;

[0008] The line sinker structure includes a sinker body and a sinker seat. The sinker body includes a cone section at the lower end and a column section at the upper end. The outer side of the column section is provided with an external thread. The sinker seat is provided with an internal threaded hole threadedly connected to the column section. The connecting rope passes through the wire hole and is fixedly connected to the sinker seat.

[0009] The shell is provided with a threaded through-hole, and the column section of the pendant can be connected to the threaded through-hole through a thread.

[0010] In this way, when the wire pendant device is needed, the servo motor drives the winding roller to rotate, loosens the connecting rope, and the wire pendant structure drops, driving the connecting rope to tighten, thereby realizing the general function of the current wire pendant device and measuring the verticality of the construction project. After the measurement is completed, the pendant body and the pendant seat are separated, and the pendant body and the shell are connected by threads to achieve the fixation of the pendant body relative to the shell. The pendant body is directly cast and formed by metal material. The servo motor drives the winding roller to rotate and winds the connecting rope, so that the pendant seat moves to the inside of the accommodating part and the pendant seat is in place. Through the split setting of the pendant body and the pendant seat, the pendant body and the pendant seat can be better matched with the shell to achieve stable installation.

[0011] The end of the column section of the pendant is concave to form a groove, and a strip-shaped protrusion is fixed in the groove.

[0012] Wherein, a supporting block is fixed in the shell, and the supporting block is provided with a supporting surface in the direction of the cone section of the pendant.

[0013] The diameter of the winding roller gradually decreases from both ends to the middle.

[0014] Among them, it also includes a clamping structure fixedly installed on the outside of the shell, the clamping structure includes a clamping arm fixedly installed on the shell, the clamping arm is L-shaped, the clamping arm is fixed with a nut, the nut is threadedly connected to a screw, one end of the screw is fixed with a handle, the other end of the screw is connected to the clamping block through a bearing, and one side of the clamping block slides in fit with the clamping arm.

[0015] In summary, the plumb line device for construction engineering has the advantages of being able to stably store the plumb line, facilitating the winding of the connecting rope, and being easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1-8 As shown, a plumb line device for construction engineering includes a housing 1, a connecting rope 2 and a plumb line structure;

[0026] The housing has a receiving cavity, and a shell cover 3 is fixed to the housing by screws. Two supports are fixed in the housing, and a winding roller 4 is rotatably installed between the supports. One end of the winding roller passes through the support and is fixedly connected to the output shaft of the servo motor 5. The servo motor is fixedly installed in the housing. The housing is concave to form a receiving portion 6. The receiving portion is penetrated by a wire hole, and one end of the connecting rope is fixedly connected to the winding roller;

[0027] The line pendant structure includes a pendant body 7 and a pendant seat 8. The pendant body includes a cone section 9 at the lower end and a column section 10 at the upper end. The outer side of the column section is provided with an external thread. The pendant seat is provided with an internal threaded hole 11 threadedly connected to the column section. The connecting rope passes through the wire hole and is fixedly connected to the pendant seat.

[0028] The shell is provided with a threaded through-hole 12, and the column section of the pendant can be connected to the threaded through-hole through threads.

[0029] In this way, when the wire pendant device is needed, the servo motor drives the winding roller to rotate, loosens the connecting rope, and the wire pendant structure drops, driving the connecting rope to tighten, thereby realizing the general function of the current wire pendant device and measuring the verticality of the construction project. After the measurement is completed, the pendant body and the pendant seat are separated, and the pendant body and the shell are connected by threads to achieve the fixation of the pendant body relative to the shell. The pendant body is directly cast and formed by metal material. The servo motor drives the winding roller to rotate and winds the connecting rope, so that the pendant seat moves to the inside of the accommodating part and the pendant seat is in place. Through the split setting of the pendant body and the pendant seat, the pendant body and the pendant seat can be better matched with the shell to achieve stable installation.

[0030] Specifically, the servo motor is connected to a servo driver, which is connected to a lithium battery through a control circuit. The lithium battery uses lithium that does not contain metallic lithium, is rechargeable, and is easy to use. It is an existing structure, and a charging port connected to the lithium battery is provided on the outer shell.

[0031] During implementation, the column section end of the pendant is concave to form a groove, in which a strip-shaped projection 13 is fixed. When the pendant is matched with the housing, the strip-shaped projection can be held and the pendant can be rotated, which facilitates the connection and disassembly of the pendant and the housing.

[0032] During implementation, a support block 14 is fixed in the housing, and the support block is provided with a contoured support surface 15 in the direction of the cone section of the pendant, so as to facilitate supporting the pendant and improve stability.

[0033] During implementation, the diameter of the winding roller gradually decreases from both ends to the middle, making it easier to wind the connecting rope.

[0034] During implementation, the device further includes a clamping structure fixedly mounted on the outside of the housing. The clamping structure includes a clamping arm 16 fixedly mounted on the housing. The clamping arm is L-shaped and fixed with a nut. The nut is threadedly connected to a screw 17. A handle is fixed to one end of the screw. The other end of the screw is connected to a clamping block 18 via a bearing. One side of the clamping block slides in contact with the clamping arm. When using the line pendant device, the clamping structure facilitates fixing the housing in the desired position. Turning the handle drives the screw to rotate, thereby pushing the clamping block to move, thereby securing the line pendant device.

[0035] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
