Description

Technical Field

[0001] This utility model relates to the field of air conditioner installation, and in particular to an installation and positioning device for an air conditioner housing used in engineering machinery. Background Technology

[0002] In the field of construction machinery, the cab space is usually very compact. When installing an air conditioner, the air conditioner housing needs to be fixed to a mounting bracket pre-welded to the cab ceiling or wall panel. The installation process typically involves one or two operators holding up the heavy air conditioner housing, attempting to align the mounting holes on its bottom mounting lugs with the threaded bolt holes on the mounting bracket, and then screwing in the bolts to secure it.

[0003] In practical operation, the following prominent technical problems exist: 1. Difficulty in alignment: Due to the narrow operating space and obstructed view, operators cannot directly see the contact surface between the air conditioner housing and the mounting bracket, relying entirely on touch for alignment, which is time-consuming and labor-intensive. 2. Low efficiency: The repeated attempts at alignment significantly prolong the installation time, especially in batch operations requiring the installation of multiple air conditioners. 3. High risk of thread damage: Forcibly screwing in bolts when the air conditioner housing is not fully aligned can easily damage or bump the bolt holes on the mounting bracket. Once the threads are damaged, repair is extremely troublesome, and may even require replacing the entire mounting bracket, causing significant losses and time delays. Therefore, there is an urgent need for an air conditioner housing installation and positioning device for engineering machinery that can solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide an installation and positioning device for an air conditioner housing used in engineering machinery, which addresses the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An installation and positioning device for an air conditioner housing used in engineering machinery includes a base plate. A slide rail is provided along the edge of the base plate, and a positioning pin module is slidably mounted on the slide rail. The positioning pin module includes a slider and a first connecting rod and a second connecting rod located on both sides of the slider. The slider slides in cooperation with the slide rail, and the first connecting rod is provided with a locking mechanism for locking the positioning pin module. The second connecting rod has a pin hole perpendicular to the base plate, and a guide pin is slidably inserted into the pin hole.

[0006] Furthermore, the locking mechanism includes a knob, a screw, and a locking plate. The first connecting rod has a threaded through hole perpendicular to the base plate, in which a screw is installed. The upper end of the screw has a knob, and the lower end of the screw has a locking plate.

[0007] Furthermore, the locking plate is circular in shape, and a rubber pad is provided at the lower end of the locking plate.

[0008] Furthermore, a damping element, which is a rubber ring, is provided in the pin hole.

[0009] Furthermore, at least two positioning pin modules are provided on the slide rail. The bottom of the slider is provided with a groove that mates with the slide rail.

[0010] Furthermore, a handle is provided on one side of the base plate. The diameter of the guide pin is smaller than the diameter of the air conditioner housing mounting bolts. A tapered guide head is provided at the end of the guide pin.

[0011] This utility model also includes other components that enable the installation and positioning device for the air conditioner housing of the engineering machinery to function properly. These devices or components all employ conventional techniques in the art. Furthermore, devices and components not specified in this utility model all employ conventional techniques in the art, such as the slide rails and sliders mentioned in this application. In specific implementation, appropriate device or component models can be selected according to the specific working scenario.

[0012] The working principle of this utility model is as follows: First, the positioning pin module on the sliding base plate slide rail is pre-adjusted. By rotating the knob of the locking mechanism to drive the screw, the locking plate presses against the base plate to achieve fixation. Then, the tapered guide head at the end of the guide pin is inserted into the bolt hole of the mounting bracket to complete the pre-positioning. Next, the fixing hole on the bottom fixing ear of the air conditioner housing is fitted into the guide pin to achieve suspension alignment, forming a precise alignment of the "fixing hole-pin hole-bolt hole" in a straight line. Finally, the guide pin is pulled out, and the entire installation and positioning device is removed to one side, allowing for direct installation of the connecting bolts.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Improved alignment accuracy: The three-hole one-line precision alignment structure solves the problem of alignment difficulties caused by visual blind spots in narrow spaces.

[0014] 2. Improved installation efficiency: The pre-positioning mechanism and suspension hole design enable rapid positioning, reducing the time spent on repeated adjustments, making it particularly suitable for batch installation operations.

[0015] 3. Avoids the risk of thread damage: Prevents damage to bolt holes caused by forced installation when not properly aligned. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example: like Figures 1-3 As shown, an installation and positioning device for an air conditioner housing 10 used in engineering machinery includes a base plate 1. A slide rail 2 is provided along the edge of the base plate 1, and a positioning pin module 3 is slidably mounted on the slide rail 2. The positioning pin module 3 includes a slider 31 and a first connecting rod 32 and a second connecting rod 33 disposed on both sides of the slider 31. The slider 31 is slidably engaged with the slide rail 2, and a locking mechanism 4 for locking the positioning pin module 3 is provided on the first connecting rod 32. A pin hole 5 perpendicular to the base plate 1 is opened on the second connecting rod 33, and a guide pin 6 is slidably inserted into the pin hole 5.

[0022] Specifically, the locking mechanism 4 includes a knob 41, a screw 42, and a locking plate 43. A damping element 7, which is a rubber ring, is provided in the pin hole 5.

[0023] In addition, the locking plate 43 is circular, and a rubber pad is provided at the lower end of the locking plate 43. At least two positioning pin modules 3 are provided on the slide rail 2. The bottom of the slider 31 is provided with a sliding groove that mates with the slide rail 2. A handle 9 is provided on one side of the base plate 1. The diameter of the guide pin 6 is smaller than the diameter of the mounting bolt of the air conditioner housing 10. A tapered guide head is provided at the end of the guide pin 6. A threaded through hole 8 perpendicular to the base plate 1 is provided on the first connecting rod 32. A screw 42 is installed in the threaded through hole 8. A knob 41 is provided at the upper end of the screw 42, and a locking plate 43 is provided at the lower end of the screw 42.

[0024] The working principle of this utility model for an installation and positioning device for an air conditioner housing used in engineering machinery is as follows: First, the positioning pin module 3 on the slide rail 2 of the sliding base plate 1 is pre-adjusted. The screw 42 is driven by rotating the knob 41 of the locking mechanism 4, causing the locking plate 43 to press against the base plate 1 for fixation. Then, the tapered guide head at the end of the guide pin 6 is inserted into the bolt hole 14 of the mounting bracket 13 to complete the pre-positioning. Next, the fixing hole 12 on the fixing ear 11 at the bottom of the air conditioner housing 10 is fitted into the guide pin 6 to achieve suspension alignment, forming a precise alignment of the three holes: fixing hole 12, pin hole 5, and bolt hole 14. Finally, the guide pin 6 is pulled out, and the entire installation and positioning device is removed to one side, allowing for direct installation of the connecting bolts.
