[0044] As Figures 1 to 5 shown, an embodiment of the present application provides a device for installing crane outriggers, including: a support body 1 and a lifting trolley 2. Among them, the support body 1 has a support plate 11 for supporting the crane and an operation chamber 12 for the operation of the lifting trolley 2, and the operation chamber 12 is located below the support plate 11. The support plate 11 is provided with an operation opening (not shown). The lifting trolley 2 is arranged in the operation chamber 12, can move in the operation chamber 12, and performs lifting operations when moving to a position relative to the crane outrigger, so as to jack the workpiece to the installation position through the operation opening and assemble the workpiece with the crane outrigger. The specific structures and connection relationships of the support body 1 and the lifting trolley 2 will be described separately below.

[0045] Specifically, in this embodiment, the support body 1 includes a support plate 11 arranged in the horizontal direction and an operation chamber 12 arranged perpendicular to the support plate 11. Among them, the support plate 11 is used to support the crane. The support plate 11 is made of steel plate and has a thickness so that it can bear the weight of the crane. The length and width of the support plate 11 can accommodate at least the length and width of the crane. The support plate 11 is provided with an operation opening, which is arranged at the middle position of the support plate 11 and distributed along the length direction of the support plate 11. The operation chamber 12 is located below the support plate 11 and is used for the operation of the lifting trolley 2. In one example, the vertical cross-section of the operation chamber 12 is U-shaped. The U-shaped operation chamber 12 is arranged opposite to the operation opening, and the two ends of the U-shaped operation chamber 12 are connected to the bottom of the support plate 11. The operation chamber 12 has a space for accommodating the lifting trolley 2. In one example, the operation chamber 12 further includes a driving ladder 121, and the driving ladder 121 is arranged on one side of the wall body forming the operation chamber 12 opposite to the operation opening. Through the driving ladder 121, it is possible to enter the operation chamber 12 from the operation opening of the support plate 11.

[0046] In this embodiment, in order to prevent the relevant components of the crane from falling into the working chamber 12 through the working opening during non-operation, a protective structure 3 is further provided. The protective structure 3 is arranged at the working opening, opens the working opening during operation, and closes the working opening during non-operation. Specifically, the protective structure 3 includes a sliding track 30, a support plate 31, pulleys 32 and a protective cover plate 34. Among them, the sliding track 30 is arranged on the support plate 11 through a bolt structure and is located on the opposite sides of the working opening along the extension direction of the working opening, that is, there are two sliding tracks 30 and they are arranged oppositely. The support plate 31 is placed in the working opening. In one example, the support plate 31 is arranged as a hollow structure, which can reduce its own weight while ensuring strength. The pulleys 32 are arranged on both sides of the support plate 31 and are slidably connected to the sliding track 30. Among them, both sides of the support plate 31 are opposite to the sliding track 30 respectively. The axial direction of the pulley 32 is horizontally arranged, and the circumferential end face of the pulley 32 abuts against the wall body of the sliding track 30 in the vertical direction. In one example, to ensure the smooth operation of the support plate 31, the pulleys 32 are respectively arranged at the four corners of the support plate 31. Guide wheels 33 are arranged on the side of the pulley 32, and the axial direction of the guide wheel 33 is perpendicular to the axial direction of the pulley 32, that is, the axial direction of the guide wheel 33 is vertically arranged, and the circumferential end face of the guide wheel 33 abuts against the wall body of the sliding track 30 in the horizontal direction. In one example, four guide wheels 33 are correspondingly arranged.

[0047] In this embodiment, the protective structure 3 further includes a protection bar 35, and the protection bar 35 is correspondingly arranged outside the sliding track 30.

[0048] The support plate 31 slides on the sliding track 30 through the pulleys 32. The protective cover plate 34 is connected to the support plate 31 to seal the working opening. When work needs to be carried out, by driving the pulleys 32, the pulleys 32 drive the support plate 31 and the protective cover plate 34 to open the working opening; when not working, by driving the pulleys 32, the pulleys 32 drive the support plate 31 and the protective cover plate 34 to seal the working opening.

[0049] In one example, in order to realize the automatic operation of the pulleys 32, a motor is further provided. The output end of the motor is connected to the pulleys 32 to drive the pulleys 32 to rotate, and then drive the self-movement of the support plate 31 and the protective cover plate 34.

[0050] The lifting trolley 2 is arranged in the working chamber 12, can move in the working chamber 12, and performs lifting operations when moving to a position relative to the crane outrigger. The workpiece is jacked up to the installation position through the working opening and the assembly of the workpiece and the crane outrigger is carried out. This crane outrigger is the fifth outrigger of the crane.

[0051] Specifically, in this embodiment, the lifting trolley 2 includes a bearing bracket 21, moving wheels 22, a working platform 23, and a lifting mechanism 24. Among them, the bearing bracket 21 has a height adapted to the working chamber 12. The moving wheels 22 are arranged at the bottom of the bearing bracket 21 and are used to drive the bearing bracket 21 to move. The working platform 23 is arranged on one side of the bearing bracket 21 and is used for manual operations on the working platform 23. In an example, the working platform 23 is arranged on the bearing bracket 21 through a lifting device so that the working platform 23 can be lifted on the bearing bracket 21 to reach the required height. Among them, the lifting device includes a driving motor, a driving wheel, a guiding wheel 33, and a lifting belt. The driving motor is installed on the bearing bracket 21, the driving wheel is connected to the output end of the driving motor, the guiding wheel 33 is arranged at the top position of the bearing bracket 21, and the lifting belt is wound around the driving wheel and the guiding wheel 33 to drive the lifting belt to rotate on the premise that the driving motor drives the driving wheel to rotate. The working platform 23 is fixedly connected to the lifting belt, and then the working platform 23 moves up and down with the lifting belt. The driving motor drives the driving wheel to rotate, causing the lifting belt to rotate, and the working platform 23 rises or falls to the specified height position with the lifting belt. Of course, in other examples, steps with different heights can be provided on the working platform 23 so that when a person stands on the steps at different heights, there are different specified height positions.

[0052] The lifting mechanism 24 is arranged at the top of the bearing bracket 21 and can lift the workpiece to the installation position for the assembly of the workpiece and the crane support leg. In this embodiment, the lifting mechanism 24 includes a scissor lift structure. In an example, the lifting platform 241 of the lifting mechanism 24 is provided with a plurality of positioning structures 242 for positioning the workpiece. The plurality of positioning structures 242 for positioning the workpiece can be the same or different to facilitate the positioning of workpieces with different structures. In an example, in order to facilitate the lifting mechanism 24 to pass through the working opening, the area of the lifting platform 241 of the lifting mechanism 24 is smaller than the area of the working opening.

[0053] When assembling the workpiece, the workpiece is placed on the lifting platform 241 of the lifting trolley 2 by an external assisting manipulator (not shown) and positioned, and then the lifting trolley 2 is manually controlled to move horizontally to the position relative to the crane support leg. Then, the workpiece is lifted to the installation position by the lifting mechanism 24, and a person steps onto the working platform 23 to install the bolts to complete the assembly. After the assembly is completed, the lifting mechanism 24 descends and resets.

[0054] In this embodiment, before assembling the crane outriggers, the crane needs to be driven onto the support plate. And in order to position and fix the crane, a vehicle stop device 4 is further provided. The stop device is arranged in a preset groove (not marked) on the support plate of the support body and is used to abut against the wheels of the crane to brake the crane. Specifically, in one example, the vehicle stop device 4 includes a receiving box groove 41, a vehicle stop plate 42 and a multi-section support link 43. Among them, the receiving box groove 41 is arranged in the preset groove on the support plate of the support body, and the preset groove on the support plate is set according to the volume of the receiving box groove 41. The setting position of the preset groove on the support plate is set according to the position of the crane relative to the working chamber. The preset grooves on the support plate are set to two and are respectively arranged opposite to the working openings of the support plate. Correspondingly, the receiving box grooves 41 are set to two. The first end of the vehicle stop plate 42 is pivotally connected to one edge of the receiving box groove 41, and the vehicle stop plate 42 can be buckled on the notch of the receiving box groove 41. After the vehicle stop plate 42 is buckled on the notch of the receiving box groove 41, the support plate forms a complete plane. The multi-section support link 43 is connected to the second end of the vehicle stop plate 42. When braking the crane, the multi-section support link 43 props up the vehicle stop plate 42. When ending the braking of the crane, the multi-section support link 43 buckles the vehicle stop plate 42 on the notch of the receiving box groove 41. The first end and the second end of the vehicle stop plate 42 are opposite to each other. In one example, the multi-section support link 43 includes a first-section support link and a second-section support link. The first-section support link and the second-section support link are pivotally connected, and the other end of the first-section support link is pivotally connected to the receiving box groove 41, and the other end of the second-section support link is pivotally connected to the second end of the vehicle stop plate 42. So that the first-section support link and the second-section support link can form a fold when the vehicle stop plate 42 is buckled and thus be placed in the receiving groove (not shown) of the receiving box groove 41.
