[0026] A refrigerated truck compartment installation and positioning device: In a specific embodiment of the present invention, a lifting frame 100 is included. The top of the lifting frame 100 is provided with a lifting lug for connecting to the hook of a lifting device. The lifting frame 100 has a first drive assembly and a second drive assembly arranged vertically at intervals. The first drive assembly is driven to be connected to two hook assemblies arranged symmetrically at intervals. The bottom surface of the refrigerated truck compartment 200 is supported on the hook assemblies. The hook assemblies are provided with clamping assemblies for contacting both ends of the refrigerated truck compartment 200. An adjustment assembly is slidably connected to the lifting frame 100. The adjustment assembly is driven to be connected to the second drive assembly. The adjustment assembly is provided with a third drive assembly. The third drive assembly is driven to be connected to a positioning assembly for detachable connection with a vehicle 300 to establish an alignment reference.

[0027] The lifting lugs on the lifting frame 100 are used to connect with the hook of the lifting equipment. The bottom surface of the refrigerated truck compartment 200 rests on the hook assembly, so that the refrigerated truck compartment 200 can be lifted using the lifting equipment and this device. The clamping assembly clamps both ends of the truck compartment 200 to prevent the truck compartment from sliding back and forth. The refrigerated truck compartment 200 is lifted above the chassis of the vehicle 300, so that the mounting holes on the bottom of the compartment are roughly aligned with the mounting points on the chassis. Then, the third drive assembly drives the positioning assembly to engage with the bottom of the vehicle 300. When the disc engages and / or abuts, and the positioning component is fixed to the vehicle 300, the mounting holes at the bottom of the compartment are aligned with the mounting points on the chassis in the left-right direction. Then, under the action of the second drive component, the lifting frame 100 and the hook assembly move along the length of the vehicle 300, so that the mounting holes at the bottom of the compartment are aligned with the mounting points on the chassis in the front-back direction. At this time, the mounting holes at the bottom of the compartment are completely aligned with the mounting points on the chassis, and the refrigerated compartment 200 can be placed on the chassis.

[0028] Beneficial effects: Only 1-2 operators are needed to complete the positioning operation by controlling the corresponding drive components through the controller, without the need for multiple people to pull and straighten the carriage, making it easy to use.

[0029] In a specific embodiment of the present invention, the hook assembly includes a hanger 400 and a hook 500. The hanger 400 is movably connected to the hanging frame 100, and the hook 500 is fixed to the bottom end of the hanger 400. The bottom surface of the refrigerated compartment 200 is supported on the hook 500, and the sides of the two hangers 400 that are close to each other are in contact with the sides of the refrigerated compartment 200.

[0030] In a specific embodiment of the present invention, the first driving assembly includes a first geared motor 600 and a first driving screw 700. The first geared motor 600 is fixedly connected to the hanging frame 100, and the first driving screw 700 is rotatably connected to the hanging frame 100. One end of the first driving screw 700 is drivenly connected to the output shaft of the first geared motor 600. Hangers 400 are respectively provided at both ends of the first driving screw 700. The first driving screw 700 passes through the top end of the hanger 400 and the two are threadedly connected. The threads at both ends of the first driving screw 700 have opposite directions. A guide rod 800 is fixed on the hanging frame 100 and slides through the hanger 400.

[0031] The first geared motor 600 starts, driving the first drive screw 700 to rotate. Since the threads at both ends rotate in opposite directions, the two hangers 400 move synchronously towards each other or synchronously away from each other along the axis of the first drive screw 700 under the constraint of the guide rod 800, thereby realizing the adjustment of the distance between the two hook assemblies and adapting to refrigerated compartments 200 of different widths.

[0032] In a specific embodiment of the present invention, the clamping assembly includes a slide rail 900, a sliding rod 1000, a clamping block 1100, and a power mechanism. The slide rail 900 is correspondingly and fixedly connected to the hanger 400. The two ends of the slide rail 900 are slidably connected to the sliding rod 1000, and both sliding rods 1000 are connected to the power mechanism. The end of the sliding rod 1000 located outside the slide rail 900 is fixedly connected to the clamping block 1100. The clamping block 1100 contacts the front and rear end faces of the refrigerated compartment 200.

[0033] In a specific embodiment of the present invention, the power mechanism includes a second reduction motor 1200 and a gear 1300. One end of the sliding rod 1000 located in the slide rail 900 is fixed with a rack 1400. The gear 1300 meshes between the two racks 1400. The gear 1300 is rotatably connected to the slide rail 900. The gear 1300 is drively connected to the output shaft of the second reduction motor 1200. The second reduction motor 1200 is fixedly connected to the slide rail 900.

[0034] The second reduction motor 1200 starts, driving the gear 1300 to rotate. The gear 1300 synchronously drives the two racks 1400 to move in opposite directions, which in turn drives the two sliding rods 1000 to extend and retract along the slide rail 900, causing the two clamping blocks 1100 to simultaneously clamp or release the front and rear end faces of the refrigerated truck compartment 200. The clamping blocks 1100 prevent the refrigerated truck compartment 200 from sliding back and forth during hoisting. The distance between the two clamping blocks 1100 corresponding to the same slide rail 900 is adjustable to accommodate refrigerated truck compartments 200 of different lengths.

[0035] In a specific embodiment of the present invention, the adjustment component includes an adjustment beam 1500, which is slidably connected to the hanging frame 100 and is drive-connected to the second drive component.

[0036] In a specific embodiment of the present invention, the second drive assembly includes a third geared motor 1600 and a second drive screw 1700. The second drive screw 1700 is rotatably connected to the hanging frame 100, and one end of the second drive screw 1700 is drively connected to the output shaft of the third geared motor 1600. The third geared motor 1600 is fixedly connected to the hanging frame 100. A drive block 1800 is threadedly connected to the second drive screw 1700, and the drive block 1800 is fixedly connected to the adjusting beam 1500.

[0037] After the positioning component is fixed to the chassis of the vehicle 300 and the left and right alignment is completed, the third reduction motor 1600 starts, driving the second drive screw 1700 to rotate. The drive block 1800 moves axially along the second drive screw 1700, causing the adjusting beam 1500 to slide back and forth relative to the lifting frame 100. Since the adjusting beam 1500 is fixed to the chassis through the positioning component, the reaction force causes the lifting frame 100 and the refrigerated compartment 200 to be finely adjusted together in the front and back direction until the holes of the refrigerated compartment 200 and the chassis are aligned front and back.

[0038] In a specific embodiment of the present invention, the positioning component includes a positioning block 1900 and a guide rail 2000. The guide rail 2000 slides through the positioning block 1900 without affecting the descent of the refrigerated compartment 200. A limiting plate 2001 is fixed at the bottom of the guide rail 2000 to prevent the positioning block 1900 from falling off.

[0039] The specific structure of the positioning block 1900 is set according to the chassis of the vehicle 300, prioritizing the structure that can be engaged with the chassis; during the positioning stage, the positioning block 1900 is engaged with the side of the chassis of the vehicle 300 and fixed relative to the chassis to establish a left-right alignment reference; when the holes are aligned and the refrigerated compartment 200 is lowered, the lifting frame 100 drives the adjusting beam 1500 and the guide rail 2000 to descend synchronously, the positioning block 1900 remains fixed with the chassis and slides relative to the guide rail 2000, without interfering with the lowering and positioning of the refrigerated compartment 200.

[0040] In a specific embodiment of the present invention, the third driving component includes a fourth reduction motor 2100, a third driving screw 2200, and a slider 2300. The third driving screw 2200 is rotatably disposed in the inner cavity of the adjusting beam 1500. The fourth reduction motor 2100 is fixed to one end of the adjusting beam 1500. The output shaft of the fourth reduction motor 2100 is connected to one end of the third driving screw 2200. The sliders 2300 are threadedly connected to both ends of the third driving screw 2200, and the threads at both ends of the third driving screw 2200 have opposite directions. The sliders 2300 are slidably connected to the inner wall of the adjusting beam 1500. The guide rail 2000 corresponds to and is fixedly connected to the slider 2300. The adjusting beam 1500 has a clearance opening for avoiding the top end of the guide rail 2000.

[0041] The fourth reduction motor 2100 starts, driving the third drive screw 2200 to rotate. The reverse threads at both ends drive the two sliders 2300 to move synchronously towards or away from each other, thereby driving the two positioning components to open and close synchronously, adjusting the distance between the two positioning blocks 1900 to adapt to vehicle chassis of different widths.

[0042] In a specific embodiment of the present invention, the refrigerated truck compartment installation and positioning device is equipped with flexible components at the parts that come into contact with the refrigerated truck compartment 200. All parts of the device that come into contact with the refrigerated truck compartment 200, including the top surface of the hook 500, the inner wall of the hanger 400, the clamping surface of the clamping block 1100, and the part where the positioning block 1900 contacts the chassis, are fixedly equipped with flexible components. These flexible components can be made of wear-resistant cushioning materials such as rubber pads or polyurethane cushioning pads. The flexible components prevent direct hard contact between metal components and the paint surface of the truck compartment or the anti-corrosion layer of the chassis, preventing scratches and coating damage during lifting, positioning, and lowering, thus protecting the product's appearance and anti-corrosion performance. Simultaneously, they increase contact friction, improve the stability of clamping and support, and reduce the risk of relative sliding of the compartment; they also buffer the impact force during lifting and lowering.

[0043] The working principle of the refrigerated truck compartment installation and positioning device of the present invention: I. Preparations before lifting and securing the refrigerated truck compartment 1. Lowering and supporting the device: The lifting equipment connects to the device through the lifting lugs on the top of the lifting frame 100, lowers the entire device, and starts the first reduction motor 600 of the first drive assembly, which drives the first drive screw 700 to rotate. Since the threads at both ends of the first drive screw 700 rotate in opposite directions, the two hangers 400 move synchronously towards each other under the constraint of the guide rod 800. The hook 500 moves to the lower surface of the refrigerated compartment 200 until the hanger 400 contacts the side of the refrigerated compartment 200.

[0044] 2. Front and rear end face clamping: Start the second reduction motor 1200 of the clamping assembly, drive the gear 1300 to rotate, and drive the sliding rod 1000 to retract along the slide 900 through the rack 1400, so that the clamping block 1100 abuts against the front and rear end faces of the refrigerated compartment 200.

[0045] II. Initial positioning after hoisting above the chassis The lifting equipment drives the refrigerated truck compartment 200 to be lifted as a whole and hoisted to the chassis of the vehicle 300. With the visual assistance of the operator, the mounting holes on the bottom of the refrigerated truck compartment 200 are roughly aligned with the mounting points on the chassis to complete the rough positioning. Then, the lifting height is kept stable, and the precise alignment process begins.

[0046] III. Precise Alignment in Two Dimensions 1. Lateral (left-right) reference positioning The fourth reduction motor 2100 of the third drive assembly is activated, driving the third drive screw 2200 to rotate. The reverse threads at both ends drive the two sliders 2300 to slide synchronously towards each other along the inner cavity of the adjusting beam 1500, causing the two guide rails 2000 and the positioning block 1900 to move synchronously, so that the positioning block 1900 is locked and abutted against the chassis, completing the lateral reference fixation. At this time, the mounting holes at the bottom of the refrigerated compartment 200 are aligned with the mounting points on the chassis in the left-right direction.

[0047] 2. Fine-tuning in the longitudinal (front-back direction) direction The third reduction motor 1600 of the second drive assembly is started, which drives the second drive screw 1700 to rotate. The threaded drive block 1800 moves along the screw axis. Since the adjusting beam 1500 is fixed to the chassis through the positioning assembly, the reaction force of the screw rotation drives the lifting frame 100 to slide relative to the adjusting beam 1500 along the length direction (front and rear direction) of the vehicle, thereby driving the refrigerated compartment 200 to make fine adjustments in the front and rear direction.

[0048] During the fine-tuning process, alignment marks or visual aids can be used to ensure that the mounting holes at the bottom of the refrigerated truck compartment 200 are aligned with the mounting points on the chassis in the front-to-back direction. At this point, the mounting holes at the bottom of the refrigerated truck compartment 200 are perfectly aligned with the mounting points on the chassis.

[0049] IV. Descending into position and disengaging from the device 1. Lowering and positioning: The lifting equipment is lowered slowly and at a constant speed, and the lifting frame 100 and the refrigerated truck 200 fall synchronously. During the descent, the positioning block 1900 remains locked to the chassis, and the guide rail 2000 slides vertically relative to the positioning block 1900 as it descends with the lifting frame 100 until the refrigerated truck 200 falls onto the chassis.

[0050] 2. Device unlocking and disengagement: After the refrigerated compartment 200 is positioned, the fourth reduction motor 2100 is started to rotate in the reverse direction, driving the two positioning blocks 1900 away from the chassis; the second reduction motor 1200 of the clamping assembly is started to rotate in the reverse direction, driving the clamping block 1100 away from the refrigerated compartment 200; the first reduction motor 600 is started to rotate in the reverse direction, driving the two lifting frames 400 away from the refrigerated compartment 200, so that the hook 500 disengages from the refrigerated compartment 200; the lifting equipment lifts the entire device away from the carrier vehicle 300.

[0051] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.
