Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building engineering equipment, in particular to a construction maintenance device. BACKGROUND

[0002] Concrete is one of the most important civil engineering materials in the contemporary era. It is a kind of artificial stone material which is prepared by mixing cementing material, granular aggregate, water, and, if necessary, additive and admixture in a certain proportion, uniformly stirring, compacting, curing and hardening.

[0003] The existing patent (publication number: CN221796642U) discloses a building construction maintenance device, which relates to the technical field of building engineering equipment, and has the technical scheme as follows: the material conveying assembly comprises a driving gear and a driven gear, the driving gear is arranged on the outer side of the rear wheel, and the driving gear and the driven gear are connected through a transmission chain.

[0004] The above-mentioned scheme can realize the effect of moving forward while turning out the geotextile for laying by setting the material conveying assembly to realize the transmission function through the rotation of the rear wheel to drive the first turning lever to pull out the geotextile when the pushing device moves forward. However, the above-mentioned scheme cannot lay the film which is wider than the width of the device itself, and the above-mentioned scheme does not have the adjusting function and cannot adapt to films of different sizes. If a relatively narrow film is laid in a relatively wide place, it needs to be laid multiple times, which greatly increases the workload, and if the joints generated during laying are not properly handled, the maintenance effect will be directly affected. Practical new type content

[0005] In view of the defects of the prior art, the application provides a construction maintenance device which has the advantages of laying films of different sizes, high practicability and the like and solves the problem that films of different sizes cannot be adapted.

[0006] To achieve the above-mentioned purpose, the application provides the following technical scheme: a construction maintenance device, comprising a machine body, two mounting blocks are fixedly connected to the bottom surface of the machine body, a compression roller is rotatably connected to the side surface of the mounting blocks which are close to each other, a threaded groove is formed in the side surface of the mounting blocks which are away from each other, the inner wall of the threaded groove and the compression roller are coaxial, a plurality of connecting blocks are arranged on the outer surface of the machine body, the connecting blocks are hexagonal in shape, a threaded rod is fixedly connected to the side surface of each connecting block, the outer surface of the threaded rod is threadedly connected to the inner wall of the threaded groove, an internally threaded pipe is fixedly connected to the end of each connecting block which is away from the outer surface of the threaded rod, the inner wall size of the internally threaded pipe is matched with the size of the threaded rod, a roller skin is rotatably connected to the outer surface of the internally threaded pipe, and an adjusting type placing mechanism is arranged on the outer surface of the machine body.

[0007] The adjusting placement mechanism comprises an assembly box fixedly connected to the outer surface of the machine body, a double-way screw rod rotatably connected to the inner wall of the assembly box, two symmetrical moving frames threadedly connected to the outer surface of the double-way screw rod, a one-way screw rod rotatably connected to the inner wall of each moving frame, and a placement plate threadedly connected to the outer surface of each one-way screw rod.

[0008] Through the above scheme, by setting the effect of the pressure roller, the film smaller than the width of the device can be laid. By rotating the threaded rod and inserting it into the inner wall of the threaded groove, the mounting block can be connected with the roller skin, thereby increasing the laying width. By setting the effect of the connecting block, the staff can quickly install and disassemble, improving the installation efficiency. If it is necessary to continue to increase the width, the threaded rod can be rotated and inserted into the threaded cavity on the side of the internal threaded tube, thereby continuously increasing the width. Thus, the width can be adjusted according to the actual situation, thereby improving the practicality of the device. By rotating the double-way screw rod, the two moving frames can move closer to or farther away from each other. By rotating the one-way screw rod, the two placement plates can move synchronously inward or outward, so that the device can adapt to different sizes of the film, thereby improving the adaptability of the device.

[0009] Further, a guide groove is formed in the outer surface of the assembly box, a communication groove is formed in the inner wall of the guide groove, and the inner wall of the communication groove is in communication with the inner wall of the assembly box. The outer surface of the double-way screw rod is slidably connected to the inner wall of the guide groove and the inner wall of the communication groove.

[0010] Through the above scheme, by setting the cooperation between the guide groove and the communication groove, the movement of the double-way screw rod can be limited and guided, so that the double-way screw rod moves more stably horizontally.

[0011] Further, a first handle is fixedly connected to the right end of the double-way screw rod, a second handle is fixedly connected to the end of each one-way screw rod away from the other, and anti-slip patterns are formed on the outer surface of the first handle.

[0012] Through the above scheme, by setting the anti-slip patterns, the staff can rotate the first handle more conveniently, thereby avoiding the phenomenon of hand slipping.

[0013] Further, anti-slip patterns are formed on the outer surface of the second handle.

[0014] Through the above scheme, by setting the anti-slip patterns, the staff can rotate the second handle without the phenomenon of hand slipping, thereby ensuring that the placement plate moves stably transversely.

[0015] Further, two electric push rods are fixedly connected to the inner wall of the machine body, a moving plate is fixedly connected to the output end of each electric push rod, four universal wheels in rectangular array are arranged on the bottom of the machine body, and the outer surfaces of the two universal wheels on the left side are fixedly mounted to the bottom surface of the moving plate.

[0016] The above solution, by setting up an electric push rod, allows the casters to retract into the machine body, thereby enabling the pressure roller and roller skin to contact the ground for laying. If movement is required, the casters can be pushed out to contact the ground, detaching the pressure roller and roller skin from the ground, thus protecting both while allowing the device to move. This greatly improves the practicality of the device.

[0017] Furthermore, a storage box is placed on the outer surface of the body.

[0018] The above solution utilizes storage boxes to store tools and rollers, making them easier for staff to use and improving their practicality.

[0019] Furthermore, a water tank is fixedly installed on the outer surface of the machine body, a water pump is fixedly installed on the upper surface of the water tank, the suction end of the water pump is inserted into the water tank, a spray head is fixedly installed on the water delivery end of the water pump, and the bottom surface of the spray head is fixedly connected to the outer surface of the machine body.

[0020] With the above method, when the water pump is started, the water inside the water tank can be transported to the inside of the spray head, and the concrete in front can be cured through the spray head.

[0021] Furthermore, both placement plates are provided with placement slots.

[0022] The above solution allows for quick placement of the film by setting up a placement plate, and its open design facilitates quick removal and placement.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This construction and maintenance device, through the action of pressure rollers, can lay films smaller than the width of the device. By rotating the threaded rod and inserting it into the inner wall of the threaded groove, the mounting block can be connected to the roller skin, thereby increasing the laying width. If it is necessary to further increase the width, the threaded rod can be rotated and inserted into the threaded cavity on the side of the internal threaded tube, thereby further increasing the width. Thus, the width can be adjusted according to the actual situation, thereby improving the practicality of the device. By rotating the bidirectional screw, the two moving frames can move closer or further apart. Combined with the rotation of the unidirectional screw, the two placement plates can move inward or outward synchronously, making the device adaptable to films of different sizes, thereby improving the adaptability of the device.
