Description

Technical Field

[0001] This utility model relates to the field of loader technology, and in particular to a beam loader. Background Technology

[0002] A bridge crane is a type of crane that spans a work area, providing lifting services typically for several tons. It consists of a crossbeam spanning the work area and supporting columns. The ends of the crossbeam rest on tall concrete columns or metal supports, resembling a bridge. Bridge cranes can easily cross the width of a workshop or warehouse and move freely, making full use of the space beneath the crossbeam to lift materials without being obstructed by ground equipment. It is the most widely used and numerous type of crane.

[0003] The crossbeams of bridge cranes need to be installed on tall concrete pillars or metal supports. Generally, crossbeam installation is completed before the factory building is topped out to meet the space requirements for hoisting. If crossbeams are installed or added to an already topped-out factory building, the installation space becomes limited, making hoisting operations inconvenient and sometimes preventing installation or requiring the removal of the factory roof. The main reason for this is that existing crossbeam installations use large cranes, and when the distance between the crossbeam and the factory roof is too small, operation becomes impossible due to space constraints. Therefore, a new type of crossbeam loader is urgently needed to solve this problem. Summary of the Invention

[0004] This utility model addresses the problems of the prior art by providing a beam loader, including a locomotive and a hydraulic power station, lifting frame, rotating frame, and locking frame installed on the locomotive. It solves the problem of limited space above the beam and the factory ceiling, while improving the safety and reliability of installation, as well as the accuracy and efficiency of installation.

[0005] Therefore, the technical solution of this utility model is a beam loader, which includes a lifting frame, a rotating frame and a locking frame. The rotating frame is rotatably connected to the lifting frame through a rotary table. The rotary table drives the rotating frame to rotate on the lifting frame. The locking frame is connected to the rotating frame through a translation slide. The translation slide drives the locking frame to translate. The locking frame is used to lock and fix the beam.

[0006] Furthermore, the lifting frame includes a lifting base frame and a lifting upper frame. The lifting base frame is fixedly connected to the locomotive, and multi-stage booster cylinders are provided in the middle of the front and rear ends of the lifting base frame and the lifting upper frame.

[0007] Furthermore, the lifting upper frame and the lifting base frame are connected by a left support rod and a right support rod, and the middle of the left support rod and the right support rod are rotatably connected by a support pivot.

[0008] Furthermore, both the left and right support rods are U-shaped support frames.

[0009] Furthermore, the lower end of the left support rod is rotatably connected to the left end of the lifting base, the upper end of the left support rod is slidably connected to the right end of the lifting upper frame, the lower end of the right support rod is slidably connected to the right end of the lifting base, and the upper end of the right support rod is rotatably connected to the left end of the lifting upper frame.

[0010] Furthermore, the lifting frame has four support legs at its four corners, and each support leg includes a support leg telescopic frame, a support leg hydraulic cylinder, and a support leg base plate.

[0011] Furthermore, two parallel translation slide rails are provided above the rotating frame, and translation sliders are provided on the translation slide rails, with translation slide tables on the translation sliders.

[0012] Furthermore, a translation hydraulic motor is installed on the translation slide, and a translation rack is provided on the inner side of the translation slide rail. The gear of the translation hydraulic motor is meshed with the translation rack.

[0013] Furthermore, locking posts are provided at the four corners of the locking frame, and locking arms are installed on the locking posts. The middle part of the locking arms is rotatably connected to the locking posts. The inner end of the locking arms is provided with anti-slip pads, and the outer end of the locking arms is connected to a locking drive cylinder.

[0014] The beneficial effects of this utility model are that, compared with the existing method of installing crossbeams by crane, the crossbeam loader of this utility model solves the problem of limited space above the crossbeam and the factory ceiling, while improving the safety and reliability of installation, avoiding problems such as crane overturning, falling loads, and collisions between the crane and other structures (such as the factory ceiling) that may occur when installing crossbeams by crane; at the same time, it improves the accuracy and efficiency of installation. When using a crane to install crossbeams, it is inconvenient and difficult to adjust the direction and position of the crossbeam, while using a crossbeam loader can precisely adjust the rotation angle and translation distance of the crossbeam through the turntable hydraulic motor and the translation hydraulic motor.

[0027] 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.

[0028] like Figures 1-10 As shown, this utility model discloses a beam loader for installing beams in a confined space. It includes a locomotive 1, on which a hydraulic power station 2 and a lifting frame 3 are installed. The hydraulic power station 2 provides hydraulic power to the hydraulic equipment on the beam loader. The lifting frame 3 is used for lifting the beam 6 during installation. A rotating frame 4 and a locking frame 5 are installed sequentially on the lifting frame 3. The rotating frame 4 is rotatably connected to the lifting frame 3 via a rotary table 38. The rotary table 38 drives the rotating frame 4 to rotate on the lifting frame 3 to achieve the rotation operation during beam 6 installation. The locking frame 5 is connected to the rotating frame 4 via a translation slide 43. The translation slide 43 drives the locking frame 5 to move translationally to achieve the translation operation during beam 6 installation. The locking frame 5 is used for locking and fixing the beam 6.

[0029] Locomotive 1 can be a powered vehicle or a non-powered trailer. When using a non-powered trailer, a separate tractor is required. Locomotive 1 serves the function of transporting and towing, and is used for transporting the crossbeam 6 during installation.

[0030] Hydraulic power station 2 is a pump station that provides hydraulic power to the hydraulic system on the beam loader. It uses hydraulic oil as a medium and delivers hydraulic oil with the required flow rate and pressure to the hydraulic system.

[0031] The lifting frame 3 is installed and fixed at the rear of the locomotive 1. The lifting frame 3 includes a lifting base frame 31 and a lifting upper frame 32. The lifting base frame 31 is fixedly connected to the locomotive 1. Multi-stage booster hydraulic cylinders 37 are provided in the middle of the front and rear ends of the lifting base frame 31 and the lifting upper frame 32. The multi-stage booster hydraulic cylinders 37 provide driving force for the lifting of the lifting upper frame 32. The two multi-stage booster hydraulic cylinders 37 provide driving force for the lifting of the crossbeam 6.

[0032] When the lifting frame 32 rises or falls relative to the lifting base frame 31, in order to ensure the stability of the lifting frame 32, the lifting frame 32 and the lifting base frame 31 are connected by a left support rod 33 and a right support rod 34. Both the left support rod 33 and the right support rod 34 are U-shaped support frames, and the middle of the left support rod 33 and the right support rod 34 are rotatably connected by a support pivot 35.

[0033] In one specific embodiment, in order to provide strong support for the lifting frame 32 when it rises or falls relative to the lifting base 31, the lower end of the left support rod 33 is rotatably connected to the left end of the lifting base 31, the upper end of the left support rod 33 is slidably connected to the right end of the lifting frame 32, the lower end of the right support rod 34 is slidably connected to the right end of the lifting base 31, and the upper end of the right support rod 34 is rotatably connected to the left end of the lifting frame 32. The sliding connection is achieved by sliding connection of slide groove and pulley.

[0034] The lifting frame 3 provides the lifting drive through multi-stage pressurized hydraulic cylinders 36 on both the front and rear sides, and ensures stability during the lifting process through the left support rod 33 and the right support rod 34. Compared with the existing crane fishing lifting method, it has better stability and higher reliability.

[0035] The lifting frame 3 has four support legs 37 at its four corners. Each support leg 37 includes a support leg telescopic frame 371, a support leg hydraulic cylinder 372, and a support leg base plate 373. The support leg telescopic frame 371 can extend outward to improve the stability of the lifting frame 31. The bottom of the piston rod of the support leg hydraulic cylinder 372 is fixedly connected to the support leg base plate 373. The support leg hydraulic cylinder 372 controls the raising and lowering of the support leg base plate 373 to achieve automatic control.

[0036] A rotary table 38 is installed in the middle of the lifting frame 32 of the lifting frame 3. The rotary table 38 includes a rotary hydraulic motor and a rotary fixed plate. The rotary table 38 is used to drive the rotating frame 4 to rotate in the lifting frame 3 so as to realize the rotation operation when the crossbeam 6 is installed.

[0037] Two parallel translation slide rails 41 are provided above the rotating frame 4. Translation slide rails 41 are provided with translation sliders 42. Translation sliders 42 are provided with translation slide tables 43. Translation slide tables 43 are slidably connected to translation slide rails 41 through translation sliders 42. Translation slide tables 43 are used for mounting and fixing locking frame 5. Translation hydraulic motors 44 are installed on translation slide tables 43. Translation racks 45 are provided on the inner side of translation slide rails 41. The gears of translation hydraulic motors 44 are meshed with translation racks 45. Translation hydraulic motors 44 drive translation slide tables 43 to perform translational movement, thereby driving locking frame 5 to perform translational movement.

[0038] To limit movement, limit blocks 46 are provided at both ends of the rotating frame 4 to limit the movement of the translation slide 43. In addition, a guard plate 47 is provided on the outside of the translation slide 41 to protect the translation slide 41.

[0039] The locking frame 5 has locking posts 51 at each of its four corners, and locking arms 52 are mounted on the locking posts 51. The middle part of the locking arm 52 is rotatably connected to the locking post 51. The inner end of the locking arm 52 is provided with an anti-slip pad, and the outer end of the locking arm 52 is connected to a locking drive cylinder 53. The cylinder body of the locking drive cylinder 53 is rotatably connected to the bottom end of the locking post 51, and the piston of the locking drive cylinder 53 is rotatably connected to the outer end of the locking arm 52. The locking drive cylinder 53 drives the locking arm 52 to open and close. The locking frame 5 achieves automated locking of the crossbeam 6 by using the locking drive cylinder 53 to drive the locking arm 52 to open and close, while providing sufficient locking force to ensure the safety of locking the crossbeam 6.

[0040] A method for loading crossbeams involves transporting the crossbeams to the installation site and then using existing crane equipment and a crossbeam loader to install them. The specific steps are as follows:

[0041] 1. After the transport vehicle carrying the crossbeam arrives at the installation site, park the crossbeam loader on one side of the transport vehicle and open the locking arm 52 of the locking frame 5.

[0042] 2. Using existing crane equipment, transfer the crossbeam from the transport vehicle to the crossbeam loader, close the locking arm 52 of the locking frame 5, and lock and fix the crossbeam.

[0043] 3. The beam loader moves to the beam installation position, and the multi-stage booster cylinder 36 drives the lifting frame 3 to rise until the beam is higher than the cement pillars or metal supports on both sides. Since the beam is lifted by the lifting frame 3, which is located below the beam, it does not occupy the space above the beam. Even when the space above the beam and the factory ceiling is limited, the beam lifting operation can still be achieved, which greatly improves the applicability of the beam loader.

[0044] 4. The rotary table 38 drives the rotating frame 4 to rotate, which in turn drives the crossbeam to rotate until the crossbeam is located on the line connecting the cement columns or metal supports on both sides.

[0045] 5. The translational hydraulic motor 44 drives the locking frame to move in translation, thereby adjusting the relative positions of the two ends of the crossbeam with the cement column or metal bracket.

[0046] 6. The multi-stage booster cylinder 36 drives the lifting frame 3 to begin descending, placing the crossbeam on the cement pillars or metal supports on both sides.

[0047] If the position and level of the crossbeam do not meet the requirements after placement, the crossbeam can be raised again and its position finely adjusted by rotation and horizontal movement to meet the installation requirements.

[0048] 7. Open the locking arm 52 of the locking frame 5, and the lifting frame 3 will reset (the multi-stage booster cylinder 36 drives the lifting frame 3 to start descending). Then the locking frame 5 will reset (close the locking arm 52 of the locking frame 5), thus completing the installation of the crossbeam.

[0049] This utility model provides a method for loading a crossbeam, which, compared to the existing method of installing crossbeams by crane grappling, solves the problem of limited space above the crossbeam and on the factory roof. It also improves the safety and reliability of the installation, avoiding problems such as crane overturning, falling loads, and collisions between the crane and other structures (such as the factory roof) that may occur when installing crossbeams by crane grappling. Furthermore, it improves the accuracy and efficiency of the installation. When using a crane to install a crossbeam, adjusting the direction and position of the crossbeam is inconvenient and difficult. Using a crossbeam loader, however, allows for precise adjustment of the crossbeam's rotation angle and translation distance via the rotary table hydraulic motor and the translation hydraulic motor.

[0050] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
