[0002] Most boom lifts currently consist of three main parts: the chassis assembly, the turntable assembly, and the boom assembly. After the chassis assembly and the turntable assembly are assembled, the boom assembly and the turntable assembly are then assembled to form a complete unit. During the assembly of the boom assembly and the turntable assembly, pins are required to connect the two together. The entire process, including lifting the pins, aligning the mounting holes, inserting the pins into the holes, and tightening, must be done manually and with precision control. This is extremely inconvenient and time-consuming. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pin pressing device for boom-type aerial work platforms, which features automated pin pressing into the hole, greatly saving manpower and time. It solves the problem that in existing technologies, the entire process of pin lifting, mounting hole alignment, pin insertion, and tightening requires manual operation and precision control, which is extremely inconvenient and time-consuming.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pressing device for a boom lift vehicle includes a main body mechanism, which comprises a boom assembly and a turntable assembly. The main body mechanism is equipped with an installation mechanism for automatically connecting the boom assembly and the turntable assembly. The installation mechanism includes a control mechanism. The installation mechanism includes a main slide rail and a slide rail connecting plate. A hydraulic cylinder slide rail is fixedly connected to the slide rail connecting plate. A hydraulic cylinder connecting seat is fixedly connected to one end of the hydraulic cylinder slide rail. A hydraulic cylinder body is fixedly mounted on the hydraulic cylinder connecting seat via a pin. A pin pressure plate is fixedly connected to the piston rod head of the hydraulic cylinder body. The pin pressure plate is slidably connected to the hydraulic cylinder slide rail via a pressure plate slider. A baffle slider and a press slider are slidably connected to the main slide rail. A baffle body is fixedly connected to the baffle slider. The baffle body is equipped with an adjustment component for adjusting and fixing its relative position.

[0005] Preferably, the adjustment assembly includes a baffle adjustment pin that is inserted after the relative positions of the baffle body and the main slide rail are adjusted and their holes are aligned, and a press adjustment pin that is inserted after the relative positions of the slide rail connecting plate and the main slide rail are adjusted and their holes are aligned.

[0006] Preferably, the control mechanism includes a panel bracket fixedly connected to the slide rail connecting plate, an operation panel is mounted on the panel bracket, and two padlocks are threadedly connected to the main slide rail.

[0007] Preferably, a pin hanger is fixedly connected to the slide rail connecting plate, and a pin to be pressed can be installed on the pin hanger.

[0008] Preferably, the control panel is electrically connected to the cylinder body.

[0009] Preferably, the two padlocks are symmetrically arranged on the main slide rail, serving as balance suspension points for the entire device.

[0010] By means of the above technical solution, this utility model provides a pressure bearing device for a boom lift vehicle, which has at least the following beneficial effects: 1. This utility model, through the installation mechanism, enables the device to automatically press the pin into the hole. By adjusting the position of the baffle and slide rail connecting plate along the main slide rail direction, it is ensured that the inner side of the baffle is roughly in close contact with the side plate of the turntable assembly. The pin to be pressed should maintain a distance of about 10mm from the side plate of the turntable assembly. Then, the press adjustment pin and the baffle adjustment pin are inserted, and the position of the baffle and slide rail connecting plate is adjusted along the main slide rail direction. After the adjustment is completed, the operator controls the control panel to slowly retract the cylinder body, which, together with the pin pressing plate, slowly pushes the pin to be pressed into the hole of the turntable assembly. Then, the operator controls the control panel to slowly press the pin into the hole of the turntable assembly, thus completing the pressing. This saves the workload of the personnel and greatly improves the simplicity of the device.

[0011] 2. This utility model, by setting an adjustment component, allows the press adjustment pin and the baffle adjustment pin to be easily adjusted and fixed to the device. The device is transported to the position of the pin to be pressed by a padlock. The pin to be pressed is placed in the pin shaft hanging belt. The pin shaft hanging belt is adjusted to keep the pin to be pressed parallel to the main body of the device. After the position of the pin to be pressed is adjusted, the device is lifted to the turntable assembly hole of the pin to be pressed. The pin to be pressed is roughly aligned with the turntable assembly hole and is in a straight line. The left and right outer plates of the turntable assembly hole are placed between the baffle and the pin to be pressed of the device. The press adjustment pin and the baffle adjustment pin are pulled out, which facilitates the pressing of the pin by the device. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the prior art, during the assembly of the boom assembly and the turntable assembly, a pin is required to connect the two together. The entire process of lifting the pin, aligning the mounting holes, inserting the pin into the holes, and tightening the pin requires manual operation and precision control, which is extremely inconvenient and time-consuming. The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a pressure pin device for a boom-type aerial work platform.

[0016] Example 1: In order to effectively improve the installation efficiency of the pin 103 to be pressed, combined with Figures 1-4 As shown, a pressure device for a boom lift is proposed. The device consists of a main body 1, which is mainly composed of a boom assembly 101 and a turntable assembly 102. The boom assembly 101 and the turntable assembly 102 are connected by a pressure pin 103. The main body 1 is provided with an installation mechanism 2, which enables the pressure pin 103 to be automatically adjusted and installed. The installation mechanism 2 is provided with a control mechanism 3, which automatically controls and adjusts the installation mechanism 2.

[0017] To automate the installation of the press pin 103, an installation mechanism 2 is proposed. This mechanism comprises a main slide rail 201 and a slide rail connecting plate 206. A hydraulic cylinder slide rail 205 is fixedly connected to the slide rail connecting plate 206. A hydraulic cylinder connecting seat 204 is fixedly connected to one end of the hydraulic cylinder slide rail 205. A hydraulic cylinder body 202 is fixedly mounted on the hydraulic cylinder connecting seat 204 via a pin. A pin pressure plate 207 is fixedly connected to the piston rod head of the hydraulic cylinder body 202. The pin pressure plate 207 is slidably connected to the hydraulic cylinder slide rail 205 via a pressure plate slider 211. A baffle slider 209 and a press slider 210 are slidably connected to the main slide rail 201. A baffle body 203 is fixedly connected to the baffle slider 209. The baffle body 203 is provided with a mechanism for... The adjusting component 208, which is used for relative position adjustment and fixing, is inserted after the relative positions of the slide rail connecting plate 206 and the main slide rail 201 are adjusted and their holes are aligned, thereby achieving relative fixation between them. Similarly, after the relative positions of the baffle body 203 and the main slide rail 201 are adjusted and their holes are aligned, the baffle adjusting pin 2081 is inserted, achieving relative fixation between them. A pin shaft hanger 104 is fixedly connected to the slide rail connecting plate 206, and a pin shaft 103 to be pressed can be installed on the pin shaft hanger 104. The device is moved to a position convenient for installing the pin shaft 103, and the pin shaft 103 is placed in the pin shaft hanger 104. The pin shaft hanger 104 is adjusted to keep the pin shaft 103 parallel to the device body, facilitating the pressing of the pin. After the position of the pressing pin 103 is adjusted, lift the device to the hole position of the turntable assembly 102 of the pressing pin 103. Roughly align the pressing pin 103 with the hole position of the turntable assembly 102, ensuring they are in a straight line. Position the left and right outer plates of the hole position of the turntable assembly 102 between the baffle body 203 and the pressing pin 103. Remove the press adjusting pin 2082 and the baffle adjusting pin 2081. Adjust the position of the baffle body 203 and the slide rail connecting plate 206 along the direction of the main slide rail 201, ensuring that the inner side of the baffle body 203 is roughly flush with the side plate of the turntable assembly 102, and that there is a gap of approximately 10mm between the pressing pin 103 and the side plate of the turntable assembly 102. Then insert the press adjusting pin 2082 and the baffle adjusting pin 2081. After adjustment, the operator controls the control panel 301 to slowly retract the cylinder body 202, which, along with the pin pressure plate 207, causes the pin to be pressed 103 to slowly enter the hole of the turntable assembly 102. By adjusting the position of the fine-tuning device, the pin to be pressed 103 is ensured to be directly facing the control when it contacts the edge of the hole of the turntable assembly 102. Then, the operator controls the control panel 301 to slowly press the pin to be pressed 103 into the hole of the turntable assembly 102. After pressing, the operator controls the control panel 301 to reset the cylinder body 202 and lift the device to the storage location, thus completing one pin pressing operation. This can automatically press the pin to be pressed 103 into the hole, replacing the original manual lifting and tightening operations, greatly saving manpower and time, and significantly improving the simplicity of the device.

[0018] To facilitate the adjustment and control of the cylinder body 202, a control mechanism 3 is proposed. A panel bracket 302 is fixedly connected to the slide rail connecting plate 206. An operation panel 301 is installed on the panel bracket 302. The operation panel 301 is electrically connected to the cylinder body 202. Two padlocks 303 are threadedly connected to the main slide rail 201. The two padlocks 303 are symmetrically arranged on the main slide rail 201 and serve as the overall balance suspension points of the device, enabling the device to be stably transported.
