Description

Technical Field

[0001] The utility model relates to production equipment, in particular to an assembly line of an arm-type aerial work platform. Background Art

[0002] The boom-type aerial work platform is a self-propelled special equipment designed to meet the needs of aerial work. The existing boom-type aerial work platform assembly line adopts a plate chain form. Among them, the plate chain form requires digging a foundation pit, placing a circulation plate in the foundation pit, with the upper part flush with the ground, and placing the semi-finished boom-type aerial work platform directly on the plate chain or on a tooling stand fixed on the plate chain. Through the circulation of the plate chain, the semi-finished boom-type aerial work platform is driven to move forward.

[0003] The plate chain type assembly line realizes cyclic operation through a closed-loop plate chain. In addition, the chassis assembly stage needs to be equipped with a tooling stand to follow the movement of the plate chain, resulting in a large demand for the main space, requiring the development of a large foundation pit in advance, with a large initial investment, and most of it is located underground, with many hidden projects and difficult maintenance. In addition, when the plate chain assembly line is used to assemble the boom aerial work platform, the chassis and the final assembly need to be consistent, resulting in a long waiting time, which reduces the production efficiency and flexibility of the production line. In addition, the tire installation process is at a relatively late position in the chassis installation process. Before the tire is installed, the semi-finished product needs to be placed on a dedicated tooling stand, and the plate chain moves the semi-finished product through the transfer stand. After the tire is installed, the semi-finished product needs to be placed directly on the plate chain. At this time, the brake device of the semi-finished product of the boom aerial work platform brakes, and the friction of the plate chain drives the semi-finished product to move, so the tooling stand needs to be removed after the tire is installed, which reduces production efficiency.

[0040] like Figures 1 to 4As shown, the arm-type aerial work platform assembly line of the utility model includes a work station, a load-bearing body 1 and a support component 2. The work station includes a chassis station and an assembly station. The support component 2 includes a first support component 201 for supporting the front and rear axles of the semi-finished arm-type aerial work platform and a second support component 202 for supporting the tires of the semi-finished arm-type aerial work platform. It also includes a track 12 for providing guidance for the load-bearing body 1. The track 12 is respectively connected to the chassis station and the assembly station. The chassis work is provided with several pairs of first support components 201, and the assembly station is provided with several pairs of second support components 202. The track 12 runs through the paired first support components 201 and the paired second support components 202. The arm-type aerial work platform assembly line of the present application is all ground engineering. Compared with the use of circulating plate chains, the initial engineering cost is lower, the later maintenance is convenient and intuitive, and the maintenance cost is reduced. The chassis station of the present application adopts the first support component 201 to support The front and rear axles of the semi-finished boom-type aerial work platform, the assembly station adopts the second support component 202 to support the wheels of the semi-finished boom-type aerial work platform, so that different support methods are adopted in different assembly states of the boom-type aerial work platform to ensure stable support and ensure that the boom-type aerial work platform is at a certain height from the ground, which is convenient for the carrier body 1 to move under the boom-type aerial work platform, thereby improving the flexibility of the carrier body 1 and realizing back and forth transportation. The track 12 does not need to be set as a circulating track, which reduces the footprint of the boom-type aerial work platform assembly line. In addition, since the carrier body 1 can be transported back and forth, it does not need to be taken off the line and manually deployed to the initial support component 2 during the production process, but moves back and forth in the track, saving turnover time and labor costs, and improving the transportation efficiency of the carrier body 1, thereby being able to reduce the number requirements of the carrier body 1 while meeting the transportation speed, and at the same time, fixed track movement ensures the high accuracy of the movement of the carrier body 1. In addition, in some specific embodiments of the present application, a carrier body 1 is respectively provided at the chassis station and the final assembly station. The carrier body 1 of the chassis station is used to transfer the semi-finished arm-type aerial work platform between two adjacent support assemblies 2 in the chassis station, and to transfer the semi-finished arm-type aerial work platform on the last pair of support assemblies 2 in the chassis station to the first pair of support assemblies 2 in the final assembly station. The carrier body of the final assembly station is used to transfer the semi-finished arm-type aerial work platform between two adjacent support assemblies 2 in the final assembly station. The carrier body 1 is operated in partitions, and the carrier bodies 1 of the base station and the final assembly station are relatively independent, thereby avoiding the requirement that the chassis and the final assembly need to be kept consistent in the circulating plate chain. In some specific embodiments, the chassis station and the final assembly station are both provided with multiple carrier bodies 1, and the functions of the carrier bodies 1 of the chassis station and the final assembly station are the same, so that the carrier bodies 1 can be interchanged, deployed, and shared at any time to reduce the impact of failures and different production rhythms of the two stations.

[0041] As a preferred embodiment, Figure 5 As shown, the first support assembly 201 includes a support unit body 7 and a support unit base 8 for supporting the front and rear axles. The support unit body 7 is detachably connected to the support unit base 8, and the support unit body 7 can be adaptively replaced for different types of boom-type aerial work platforms.

[0042] As a preferred embodiment, Figure 5 As shown, the support unit body 7 includes a support plate 701 for supporting the front and rear axles, a connecting piece 702 and a main body base 703. The upper surface of the support plate 701 is a plane for abutting against the front and rear axles of the semi-finished arm-type aerial work platform. Since the semi-finished arm-type aerial work platform has a low requirement on the structural strength of the support unit body 7 during the assembly of the chassis, the main body base 703 is connected to the main body base 703 by a plurality of connecting pieces 702. The main body base 703 can be detachably installed on the support unit base 8, so that the support unit body 7 has a low cost while meeting the structural strength requirements.

[0043] As a preferred embodiment, Figure 5 As shown, a plurality of bolts are arranged on the support unit base 8, and mounting holes corresponding to the plurality of bolts are formed on the main base 703, so as to be locked on the bolts by double nuts respectively located at both ends of the mounting holes. By adjusting the height of the double nuts located at both ends of the mounting holes, the height of the first support mechanism can be changed, thereby changing the placement height of the boom-type aerial work platform, thereby ensuring that the supporting vehicle body 1 can pass through from below when the boom-type aerial work platform assembly line produces different types of boom-type aerial work platforms.

[0044] As a preferred embodiment, Figure 5 As shown, the main body base 703 is provided with a plurality of reinforcing plates 704 to improve the structural strength of the supporting unit main body 7 and prevent the supporting unit main body 7 from being damaged by force.

[0045] As a preferred embodiment, Figure 5 As shown, the connecting member 702 is a box-shaped connecting member to improve the connection strength between the support plate 701 and the main base 703.

[0046] As a specific implementation method, Figure 6 As shown, the weight of the boom aerial work platform in the final assembly stage is relatively heavy, and the structural strength requirements for the second support assembly are relatively high. Therefore, the second support assembly includes a support block 9, and the upper surface of the support block 9 is a plane. The semi-finished boom aerial work platform is locked by a braking device and placed on the upper surface of the support block 9. An additional stop structure may also be provided to prevent the semi-finished boom aerial work platform from moving forward and backward after the tire is installed, or an anti-slip pattern may be formed on the upper surface of the support block 9 to increase the friction between it and the tire.

[0047] As a preferred embodiment, Figure 6 As shown, the upper surface of the support block 9 located at the end of the final assembly station is configured to be suitable for supporting the front wheels and rear wheels of the semi-finished boom-type aerial work platform, and the end of the support block 9 away from the final assembly station is provided with a slope, so that after completing the installation of the last assembly link of the final assembly station and the power-on test, it can drive away by itself. In some specific embodiments, the support block 9 includes a first support block for supporting the front wheel and a second support block for supporting the rear wheel, and the main board 701 includes a first support plate for supporting the front axle and a second support plate for supporting the rear axle, wherein the length of the second support block is greater than the length of the first support block, and the length of the second support plate is greater than the length of the first support plate. When the carrying body 1 transports the semi-finished boom-type aerial work platform, the front axle is placed on the first support plate. Since the second support plate is longer in length, it can adapt to boom-type aerial work platforms with different bridge distances. The front wheel is placed on the first support block. Since the second support block is longer in length, it can adapt to boom-type aerial work platforms with different bridge distances.

[0048] As a specific implementation method, the load-bearing vehicle body 1 is provided with a lifting device for carrying workpieces. The lifting device can be a hydraulic lifting device. The hydraulic lifting device includes a lifting platform and a cylinder for driving the lifting platform to lift. The hydraulic lifting device requires lifting and lowering synchronization. In the static state after the cylinder is lifted, a hydraulic lock and an accumulator device are used to ensure that the cylinder and the lifting platform do not sink when fully loaded to ensure safety. The load-bearing vehicle body 1 can be equipped with a high-power power battery, and the battery management system is relied on to perform functions such as battery charging management, process monitoring, and overvoltage protection. The load-bearing vehicle body 1 can be provided with multiple safety protections, including optical sensor obstacle avoidance, mechanical anti-collision, emergency stop, motor failure button, etc. In some embodiments, there are sound and light reminders when the load-bearing vehicle body 1 is started to warn other personnel to pay attention to safety. In some embodiments, the arm-type aerial work platform assembly line also includes a main control cabinet, and a liquid crystal touch screen is provided on the main control cabinet, through which the operating status of the load-bearing vehicle body 1 in the track 12 can be displayed. When the system fails, the screen can automatically release relevant warning pictures or sentences. When abnormal conditions such as power failure, lifting abnormality, and misoperation occur, corresponding protection measures are implemented, and sound and light alarms are performed.

[0049] As a specific implementation manner, the carrier vehicle body 1 is an RGV vehicle or an AGV vehicle, and the RGV vehicle is preferably used. The RGV vehicle has a low initial cost, a low failure rate, and a low subsequent maintenance cost.

[0050] It can be seen from the above description that the advantages of the utility model are, first, the use of a load-bearing vehicle for transportation occupies little space, has low initial costs, and is convenient for later maintenance; second, a support assembly is provided to ensure that the load-bearing vehicle can pass under the semi-finished product of the arm-type aerial work platform, thereby reducing turnover time and improving production efficiency; third, the fixed track movement enables the load-bearing vehicle to move with high precision; fourth, the chassis and the final assembly are relatively independent, thereby improving the flexibility of the assembly line of the arm-type aerial work platform.

[0051] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
