Technical Field

[0001] The present application relates to the technical field of construction engineering, and specifically to a construction engineering management quality acceptance device. Background Art

[0002] The quality of construction project management refers to ensuring that the quality of the project meets the design requirements, technical standards and relevant laws and regulations and achieves the expected quality goals through reasonable organization, standardized management and effective control at all stages of the construction project. The magnetic plumb bob is an instrument that measures verticality by using the principle that the deadweight of the plumb line forms a vertical line. It is a common quality acceptance device used in construction project management and is widely used in construction.

[0003] The Chinese utility patent with announcement number CN221571509U discloses a construction project management quality acceptance device. Through the linkage between a first adjusting knob, a connecting shaft, a wire take-up reel, a nylon rope, a threaded rod, a pulley, a belt, a first nut pair and a threading block, the wire take-up reel and the threaded rod are driven to rotate by rotating the first adjusting knob, so that the required wire length can be accurately achieved.

[0004] This solution provides a clamping and fixing operation for the plumb bob through a clamping block, thereby fixing the plumb bob inside the shell. However, this fixing method has certain defects. If the force of clamping the plumb bob is not enough, the plumb bob will fall off when subjected to force. If the clamping force of the plumb bob is too great, the surface of the plumb bob will be worn due to tight contact.

[0005] Therefore, the present application provides a construction project management quality acceptance device to solve the above problems. Utility Model Content

[0006] The present application provides a construction project management quality acceptance device, which aims to solve the problem raised in the background art that there are certain defects in fixing the plumb bob inside the shell.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solution: a construction project management quality acceptance device, comprising a housing and a wire take-up assembly disposed inside the housing, wherein a base is mounted at the lower end of the housing, a limit mechanism is disposed inside the housing, and a plumb bob is disposed at the lower end of a nylon rope on the wire take-up assembly;

[0008] The limiting mechanism includes rail frames symmetrically arranged inside the shell and a limiting plate slidably installed between the two rail frames, a connecting shell arranged at the upper end of the plumb bob and a positioning plate fixedly installed at the upper end of the connecting shell. The connecting shell is provided with a limiting groove for the insertion of the limiting plate. The wire-reeling assembly is an existing equipment device in the comparative scheme. It can be connected to the positioning plate through a nylon rope to realize the recovery of the plumb bob. The limiting plate is an elongated strip as a whole and is provided with a U-shaped groove. The U-shaped groove is adapted to the connecting shell and can realize the function of inserting the limiting groove to complete the limiting and fixing function.

[0009] Preferably, a servo motor is provided on the outside of the shell, and the output end of the servo motor is fixedly connected to a threaded rod, the threaded rod is provided on the inner side of the rail frame, and a positioning rod is provided on the inner side of the rail frame away from the threaded rod. The internal circuit connection of the servo motor is an existing technology. The servo motor drives the limit plate to move between the two rail frames by driving the threaded rod to rotate. When the limit plate moves toward the end away from the servo motor, it no longer limits the plumb bob.

[0010] Preferably, a threaded hole for threadedly sleeved on the threaded rod is formed on the limiting plate, and a positioning hole for movably sleeved on the positioning rod is formed on one end of the limiting plate away from the threaded hole.

[0011] Preferably, the upper end of the plumb bob is fixedly connected with a boss, and the connecting shell is provided with a threaded groove for threaded connection of the boss at one end close to the plumb bob. The connecting shell and the boss on the plumb bob are threadedly sleeved, and the plumb bob and the connecting shell can be conveniently disassembled later for regular maintenance of the plumb bob.

[0012] Preferably, the upper end of the positioning plate is connected to the nylon rope on the take-up assembly.

[0013] Preferably, a fixing plate and an anti-slip plate fixedly installed between the two fixing plates are symmetrically installed on the limiting plate, and the fixing plate is slidably connected to the outer side of the rail frame.

[0014] The acceptance device is configured with a limiting mechanism inside a shell and a connecting shell installed on the plumb bob. A rail frame, a servo motor, a threaded rod and a limiting plate cooperate to achieve limiting fixation by inserting the limiting plate into the limiting groove after the plumb bob is recovered into the shell through the nylon rope on the take-up assembly and the connecting shell is between the two rail frames. Compared with the traditional clamping and fixing method, the limiting and fixing method is simpler and will not cause wear to the plumb bob.

[0015] The acceptance device is configured with fixing plates on both sides of the limit plate and an anti-slip plate fixed between the two fixing plates. After the limit plate is inserted into the limit groove and fixed, the anti-slip plate is located at the outlet of the base, thereby achieving anti-slip and sealing protection. This can prevent the plumb bob from accidentally falling off, reduce the entry of water vapor through the sealed outlet, and increase the service life of the plumb bob.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] This embodiment provides a construction project management quality acceptance device, such as Figure 1-6 As shown, the acceptance device includes a housing 1 and a wire take-up assembly 3 disposed inside the housing 1. A base 2 is mounted on the lower end of the housing 1. A limit mechanism 4 is disposed inside the housing 1. A plumb bob 5 is disposed on the lower end of the nylon rope on the wire take-up assembly 3.

[0034] The limiting mechanism 4 includes rail frames 41 symmetrically arranged inside the shell 1 and a limiting plate 45 slidably installed between the two rail frames 41, a connecting shell 51 arranged at the upper end of the plumb bob 5, and a positioning plate 53 fixedly installed at the upper end of the connecting shell 51. A limiting groove 52 is provided on the connecting shell 51 for the limiting plate 45 to penetrate.

[0035] Specifically, the take-up assembly 3 is an existing equipment device in the comparative scheme, which can be connected to the positioning plate 53 through a nylon rope to realize the recovery of the plumb bob 5. The limiting plate 45 is an elongated strip as a whole and has a U-shaped groove. The U-shaped groove is adapted to the connecting shell 51 and can realize the function of limiting and fixing the limiting groove 52 by inserting it. There are two rail frames 41 and they are symmetrically distributed inside the shell 1. The limiting plate 45 is installed between the two rail frames 41 by sliding to realize guided movement.

[0036] A servo motor 42 is provided on the outside of the shell 1, and a threaded rod 43 is fixedly connected to the output end of the servo motor 42. The threaded rod 43 is provided on the inner side of the rail frame 41, and a positioning rod 44 is provided on the inner side of the rail frame 41 away from the threaded rod 43. A threaded hole 46 for threaded sleeve with the threaded rod 43 is provided on the limiting plate 45, and a positioning hole 47 for movably sleeved with the positioning rod 44 is provided on the end of the limiting plate 45 away from the threaded hole 46.

[0037] More specifically, the internal circuit connection of the servo motor 42 is an existing technology. The servo motor 42 drives the limit plate 45 to move between the two rail frames 41 by driving the threaded rod 43 to rotate. When the limit plate 45 moves toward the end away from the servo motor 42, it no longer limits the plumb bob 5. When the limit plate 45 moves toward one end of the servo motor 42, it can provide a limit fixation for the plumb bob 5. The positioning rod 44 is movably inserted into the positioning hole 47. The limit plate 45 plays a role in improving stability when moving through the threaded rod 43, thereby reducing the vibration amplitude during movement.

[0038] The upper end of the plumb bob 5 is fixedly connected to a boss, and a threaded groove for threaded connection of the boss is opened at one end of the connecting shell 51 close to the plumb bob 5. The upper end of the positioning plate 53 is connected to the nylon rope on the take-up assembly 3.

[0039] It should be noted that the connecting shell 51 and the protruding column on the plumb bob 5 are threaded together, so that the plumb bob 5 and the connecting shell 51 can be easily separated in the future for regular maintenance of the plumb bob 5.

[0040] A fixing plate 61 and an anti-slip plate 6 fixedly installed between the two fixing plates 61 are symmetrically mounted on the limiting plate 45 . The fixing plate 61 is slidably connected to the outer side of the rail frame 41 .

[0041] It is worth mentioning that the anti-slip plate 6 is located at the exit of the base 2, which has realized anti-slip and sealing protection, which can not only prevent the plumb bob 5 from accidentally falling off, but also reduce the entry of water vapor through the sealed exit, thereby improving the service life of the plumb bob 5.

[0042] During use, the shell 1 is moved to the engineering project where the verticality needs to be measured. When testing is required, the servo motor 42 is started, and the servo motor 42 drives the threaded rod 43 to rotate, so that the limit plate 45 fixed to the plumb bob 5 is moved away, and the fixed plate 61 and the anti-slip plate 6 installed on the limit plate 45 move synchronously and no longer block the opening of the base 2. At this time, the motor on the take-up assembly 3 is started, and the plumb bob 5 can be used to perform the verticality measurement operation. After the measurement operation is completed, the take-up assembly 3 is recovered to the inside of the shell 1 by the motor-driven plumb bob 5, and then the limit plate 45 cooperates with the limit groove 52 on the connecting shell 51 to complete the insertion and limit fixation.

[0043] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
