[0036] The aerial work platform is a platform type device for carrying workers, tools and materials to high altitude work position, which has the advantages of improving the efficiency and safety of indoor and outdoor high altitude work. The aerial work platform can be divided into vehicle-mounted type, scissor type, straight arm type, curved arm type and spider type. For non-scissor type aerial work platform, because the aerial work platform will generate a large overturning moment during the arm frame amplitude and telescopic process, the counterweight is a key component to ensure the stability of the whole vehicle. Generally, the counterweight is connected at the tail of the rotary table to control the center of gravity of the aerial work platform, thereby ensuring the stability of the whole vehicle.

[0037] However, the structure and weight of the counterweight block are generally matched with a single type of aerial work platform, which limits its compatibility and the universality of the counterweight block is poor. Different molds are needed for the production of different counterweight blocks, which also leads to high production cost of the counterweight block.

[0038] In view of the above technical problems, the application provides a counterweight block and an aerial work platform to improve the universality of the counterweight block and reduce the cost of the aerial work platform. The overall structure, working principle and technical effects of the counterweight block and the aerial work platform provided by the application are described in detail below through embodiments and in conjunction with the drawings.

[0039] Please refer to Figure 1 and Figure 2 The utility model provides a counterweight 100 for aerial work platform to control the center of gravity of aerial work platform, ensure the overall stability of aerial work platform, avoid the aerial work platform under the action of the overturning torque generated in the process of arm frame amplitude and telescopic and lead to overturning. Meanwhile, the counterweight 100 provided by the utility model is convenient to dismount and install, can be adapted to different models of aerial work platform, improve its compatibility and universality, and reduce production cost.

[0040] The counterweight 100 provided by the utility model includes first shell 110, second shell 120, communication part 130 and receiving plate 140, first shell 110 and second shell 120 are same in structure and are hollow, first shell 110 and second shell 120 are opposite and have interval between them. The communication part 130 is connected at the lower end of first shell 110 and second shell 120, and the inside of communication part 130 is also hollow, so that the inside space of first shell 110, second shell 120 and communication part 130 is communicated and forms filling cavity 101 together, and the filling cavity 101 is used to fill counterweight. The receiving plate 140 is Z-shaped plate body, and the receiving plate 140 has lower end horizontal section 141, vertical section 142 and upper end horizontal section 143 connected in sequence, wherein the lower end horizontal section 141 and the upper end horizontal section 143 are opposite. Figure 5 Further, installation groove 150 is formed on the side of first shell 110 close to second shell 120 and the side of second shell 120 close to first shell 110, and the installation groove 150 has an opening for the entry and exit of rotating table 200, so that the installation groove 150 is used for the entry of rotating table 200 and for accommodating rotating table 200. The lower end horizontal section 141 extends into the filling cavity 101, and the upper end horizontal section 143 and the vertical section 142 are respectively attached to the two inner walls of the installation groove 150, and the upper end horizontal section 143 and the vertical section 142 are fixedly connected to the two inner walls of the installation groove 150. The upper end horizontal section 143 is provided with a connecting part 160 for detachable connection with the rotating table 200.

[0041] It can be understood that the counterweight in the filling cavity 101 can be selected according to actual working conditions and construction requirements. During the moving, transporting and transferring process of the aerial work platform, the counterweight 100 can be detached from the aerial work platform, and at the same time, the filling cavity 101 can not be filled with counterweight, so as to reduce the overall quality of the aerial work platform, and further reduce the energy consumption in the moving process. After reaching the construction site, the counterweight 100 is assembled, and the mass of the counterweight can also be selected according to the actual construction load, so as to determine the volume of the counterweight to be poured in the filling cavity 101, and select counterweights of different materials. Different materials such as sand and iron sand with different densities can be selected for different loads.

[0042] By setting the filling cavity 101 inside the first shell 110, the second shell 120 and the communication part 130, and filling the counterweight bodies of different masses inside the counterweight 100, the adaptability of the aerial work platform is achieved by adapting to different loads of the aerial work platform, and the applicability is improved. Meanwhile, the counterweight 100 is detachably arranged on the rotating table 200, so that the counterweight 100 can be connected to different models of aerial work platforms through the rotating table 200, and different masses of counterweight bodies can be adjusted for different aerial work platforms, so as to improve the versatility of the counterweight 100 and reduce the cost.

The through holes are formed in the mounting plate 161 and communicated with the nuts. The rotating table 200 is moved into the mounting groove 150 and attached to the mounting plate 161. Then, the detachable connection between the rotating table 200 and the mounting plate 161 is realized through the cooperation of the bolts and the nuts. In other optional embodiments, the detachable connection between the mounting plate 161 and the rotating table 200 can also be realized through the pin shaft connection, the flange connection and the like.
