Description

Technical Field

[0001] This utility model relates to the technical field of spraying polyurethane insulation layer on the interior walls of cold storage, specifically a spraying equipment for polyurethane insulation layer on the interior walls of cold storage. Background Technology

[0002] Polyurethane insulation spraying is a spraying technology that involves directly spraying a mixture onto the inner wall of a cold storage facility using a spray gun, causing it to foam and form a solid structure. Rigid polyurethane foam is a high-density, closed-cell foam compound with a closed-cell rate ≥95%, a water absorption rate ≤1%, and a thermal conductivity ≤0.022W / mk. Therefore, it possesses excellent thermal insulation properties and is widely used in cold storage and other applications requiring insulation.

[0003] The existing polyurethane spraying construction mainly relies on manual spraying of the inner wall of cold storage with handheld spray guns. This is not only time-consuming and labor-intensive, but also makes it difficult to observe the spray thickness during spraying because polyurethane foaming takes a certain amount of time, resulting in difficulty in ensuring the uniformity of manual spraying. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a polyurethane insulation layer spraying equipment for the interior walls of cold storage, so as to solve the problems of low efficiency and difficulty in ensuring uniformity of polyurethane spraying.

[0005] The technical solution adopted by this utility model is: a polyurethane insulation layer spraying equipment for the interior wall of a cold storage, including a spraying host, a pipe assembly and a spray gun. The spray gun is connected to the spraying host through the pipe assembly. It also includes a mobile vehicle, on which a lifting platform is installed. The spraying host is installed on the mobile vehicle, and a support frame for installing the spray gun is provided on the lifting platform.

[0006] The above structure has the following beneficial effects:

[0007] 1. The spray gun is mounted on the mobile vehicle via a support frame, allowing it to move up and down with the lifting platform. This ensures stable polyurethane spraying of the interior walls of the cold storage, improving both spraying efficiency and uniformity.

[0008] 2. The spraying unit is installed on a mobile vehicle, which allows the spraying unit and spray gun to move together with the mobile vehicle, improving the overall equipment transfer efficiency. This enables the spraying equipment to be flexibly moved to various locations for spraying, further improving spraying efficiency and reducing the labor intensity of workers.

[0009] Preferably, the lifting platform is further provided with a horizontal moving component for moving the support frame. The horizontal moving component includes a mounting plate and a first driving mechanism. The first driving mechanism is mounted on the mounting plate, and the support frame is connected to the first driving mechanism.

[0010] The horizontal moving component drives the support frame to move along the mounting plate through the first drive mechanism, so that the spray gun moves horizontally along with the support frame. In this way, the spray gun can also move horizontally during the lifting and lowering process, thereby increasing the spraying area during a single lifting and lowering, and further improving the spraying efficiency of the spraying equipment.

[0011] Preferably, the mounting plate is also connected to a pitch assembly, which includes a rotating bracket and a second drive mechanism. The mounting plate is rotatably connected to the rotating bracket, and the mounting plate is connected to the lifting platform through the second drive mechanism.

[0012] The pitch assembly drives the mounting plate to rotate around the rotating bracket via the second drive mechanism, thereby allowing the spray gun to be pitched and adjusted to adapt to different spraying environments. For example, on a sloping roof, the pitch angle of the spray gun can be adjusted to make the spray gun spray the roof surface more stably. Or at the junction of the wall and the ground, the spray gun can be adjusted downwards to effectively spray the surface, thereby improving the spraying effect.

[0013] Preferably, a ranging sensor is also mounted on the mounting plate.

[0014] The distance sensor can monitor the distance between the lifting platform and the wall, so as to control the distance between the lifting platform and the wall. This ensures that the distance between the spray gun and the wall is the same after each adjustment of the moving vehicle position, thereby ensuring that the spray thickness is the same each time, making the polyurethane insulation layer more uniform and improving the spraying effect.

[0015] Preferably, the support frame is equipped with a buckle, and the spray gun is detachably connected to the support frame via the buckle.

[0016] The detachable clips connecting the spray gun and the support frame allow the spray gun to be flexibly disassembled according to the actual situation. When the spraying environment is complex and not suitable for automatic spraying, the spray gun can be removed and the workers can perform manual spraying, which is more flexible and can adapt to different spraying situations.

[0017] Preferably, the lifting platform is equipped with a railing.

[0018] The lifting platform is surrounded by a fence, which allows workers to stand on the platform to perform manual operations. The fence ensures the safety of workers during manual spraying.

[0019] Preferably, the horizontal moving component is also connected to a torsion component, which includes a torsion platform installed between the support frame and the first driving mechanism and push rods installed on both sides of the mounting plate. The torsion platform is provided with a support shaft, and the support frame has a hole that matches the support shaft. The support frame is rotatably connected to the torsion platform through the support shaft.

[0020] When the support frame moves to the edge of the mounting plate along with the horizontal moving component, the push rods on both sides of the mounting plate push the sides of the support frame, causing the support frame to rotate on the torsion platform. This causes the spray gun to rotate around the support axis within a certain range, thereby increasing the spraying range that the spray gun can spray and further improving the spraying efficiency.

[0021] Preferably, an elastic element is also provided between the torsion platform and the support frame.

[0022] The elastic element can be a torsion spring, which allows the support frame to automatically reset after leaving the push rod range, returning to a position facing the wall, so as to facilitate more stable and precise spraying.

[0023] Preferably, the end of the push rod is rotatably connected to a roller.

[0024] By installing rollers at the end of the push rod, the rollers can abut against the support frame, thereby reducing the friction between the push rod and the support frame and increasing its service life. Attached Figure Description

[0035] The components include: spray gun 10, mobile vehicle 20, lifting mechanism 21, lifting platform 30, fence 31, support frame 40, buckle 41, lock 42, horizontal movement component 50, mounting plate 51, first drive mechanism 52, distance sensor 53, pitch component 60, rotating bracket 61, second drive mechanism 62, torsion platform 71, push rod 72, support shaft 73, and roller 74. Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] According to the instruction manual Figure 1-6 As shown, this utility model provides a polyurethane insulation layer spraying equipment for the interior wall of a cold storage, including a mobile vehicle 20, a spraying host, a spray gun 10, and a pipe assembly for connecting the spray gun 10 and the spraying host. The spraying host is installed inside the mobile vehicle 20, and a scissor-type lifting mechanism 21 is installed on the mobile vehicle 20. A lifting platform 30 is installed on the top of the lifting mechanism 21, and a pitch component 60, a horizontal movement component 50, and a support frame 40 for installing the spray gun 10 are installed on the lifting platform 30.

[0039] In this embodiment, the mobile vehicle 20 is also equipped with a control system and a controller for controlling the movement of the mobile vehicle 20. At the same time, the lifting mechanism 21, the spraying host and the spray gun 10 are also connected to the control system and controller. The controller can control the movement and operation of the entire spraying equipment, which is more convenient.

[0040] In this embodiment, the horizontal moving component 50 includes a mounting plate 51 and a first driving mechanism 52 mounted on the mounting plate 51. The support frame 40 is connected to the first driving mechanism 52. The first driving mechanism 52 is a linear motor. The first driving mechanism 52 drives the support frame 40 to move horizontally on the mounting plate 51. The linear motor can achieve uniform and precise positioning, which improves the spraying efficiency and spraying uniformity.

[0041] In this embodiment, the pitch assembly 60 includes a rotating bracket 61 and a second drive mechanism 62. The rotating bracket 61 is mounted on the lifting platform 30, and the mounting plate 51 is rotatably connected to the rotating bracket 61. One end of the second drive mechanism 62 is rotatably connected to the lifting platform 30, and the other end of the second drive mechanism 62 is rotatably connected to the mounting plate 51. The second drive mechanism 62 adopts an electro-hydraulic push rod 72. The second drive mechanism 62 pushes the mounting plate 51 to rotate around the rotating bracket 61, thereby realizing the pitch angle adjustment of the spray gun 10. This allows the equipment to adjust its pitch angle when spraying on inclined roofs or other similar surfaces, so that the spray gun 10 can be perpendicular to the inclined roof, thereby further improving the uniformity of the spraying.

[0042] In this embodiment, a buckle 41 is rotatably connected to the support frame 40, and a lock 42 that cooperates with the buckle 41 is also rotatably connected to the support frame 40. A torsion spring is installed between the lock 42 and the support frame 40. When the buckle 41 rotates to the position where it cooperates with the lock 42, the lock 42 can lock the buckle 41 onto the support frame 40 under the action of the torsion spring, thereby fixing the spray gun 10. At the same time, it can be unlocked by simply pressing the lock 42, so that the spray gun 10 can be easily taken out for workers to manually spray. In addition, a railing 31 is also provided on the lifting platform 30 to protect the workers standing on the lifting platform 30 and prevent them from being injured during work.

[0043] In this embodiment, a distance sensor 53 is also installed on the mounting plate 51, and the distance sensor 53 is also connected to the control system. The distance sensor 53 can monitor the distance between the lifting platform 30 and the wall, so as to control the distance between the lifting platform 30 and the wall. This ensures that the distance between the spray gun 10 and the wall is the same after each adjustment of the position of the moving vehicle 20, thereby ensuring that the spray thickness is the same each time, making the thickness of the polyurethane insulation layer more uniform and improving the spraying effect.

[0044] Its working principle is as follows: when it is necessary to spray the wall of the cold storage, the controller controls the trolley to move to the wall and starts the spraying host and spray gun 10. During the spraying process of the spray gun 10, the first drive mechanism 52 drives the spray gun 10 to reciprocate in the horizontal direction, while the lifting mechanism 21 drives the spray gun 10 to move up or down, thereby achieving the effect of automatic spraying of the wall. When spraying the sloping roof or the bottom of the wall below the spray gun 10, the second drive mechanism 62 drives the mounting plate 51 to tilt, adjusting the tilt angle of the spray gun 10 to better carry out the spraying work. If it is found that the spraying quality of some areas is not up to standard, or if the complex surface is not suitable for automatic spraying, the buckle 41 can be disassembled, the spray gun 10 can be taken out, and the worker can perform manual spraying to improve the spraying effect.

[0045] Example 2

[0046] According to the instruction manual Figure 7-10 As shown, the difference between this embodiment and Embodiment 1 is that a torsion assembly is also installed on the horizontal moving assembly 50. The torsion assembly includes a torsion platform 71 and a push rod 72. The torsion platform 71 is located between the first driving mechanism 52 and the support frame 40. The torsion platform 71 has a circular groove and a support shaft 73 is provided in the middle of the torsion platform 71. The bottom of the support frame 40 has a hole that cooperates with the support shaft 73, and the outer periphery of the support frame 40 is arc-shaped, so that the support frame 40 can rotate on the torsion platform 71. The push rod 72 is installed on both sides of the mounting plate 51, and the end of the push rod 72 can abut against the side of the support frame 40, thereby pushing the support frame 40 to rotate through the push rod 72.

[0047] In this embodiment, an elastic element is also installed between the torsion platform 71 and the support frame 40. The elastic element is a torsion spring, which enables the support frame 40 to automatically reset after leaving the range of the push rod 72 and return to the state facing the wall, so as to facilitate more stable and precise spraying.

[0048] In this embodiment, a roller 74 is rotatably connected to the end of the push rod 72, which enables the roller 74 to abut against the support frame 40, thereby reducing the friction between the push rod 72 and the support frame 40 and improving its service life.

This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are within the scope of protection of this utility model.
