The trolley mainly includes a gantry system 1, a ladder platform system 2 arranged above the gantry system 1, and a travel system 3 arranged at the bottom of the gantry system 1. At least one hydraulic extrusion clamp 4 is respectively arranged on both sides of the gantry system 1. The hydraulic extrusion clamp 4 is used as an actuator to squeeze and deform the side wall ribbed steel bars and sleeves on both sides of the trolley and connect them together.

[0049] In this embodiment, the hydraulic squeezing pliers 4 are connected to the gantry system 1 through a set of displaceable mechanical mechanisms, so that the hydraulic squeezing pliers 4 have a longitudinal, transverse and / or vertical displacement stroke on the gantry system 1, thereby expanding the construction range of the hydraulic squeezing pliers 4, and at the same time, there is no need to manually carry the 30-40kg hydraulic squeezing pliers 4 for operation, and a single person can perform the steel sleeve docking operation, thereby reducing labor costs, reducing the labor intensity of on-site workers, and improving on-site construction efficiency. Among them, the longitudinal direction refers to the length direction of the gantry system 1, the transverse direction refers to the width direction of the gantry system 1, and the vertical direction refers to the height direction of the gantry system 1.

[0050] In this embodiment, the mechanical mechanism for realizing the longitudinal, transverse and / or vertical displacement of the hydraulic pressing jaws 4 has various implementation modes.

[0051] refer to Figures 2 to 4 In the first embodiment, the mechanical mechanism includes a fixing rod 5 and a first track 6, specifically:

[0052] There are multiple fixing rods 5, which are fixedly connected to the longitudinal beam of the portal system 1 at intervals in the longitudinal direction, and the length direction of the fixing rods 5 is parallel to the transverse direction, and the first rails 6 are fixedly connected to each fixing rod 5, so that the first rails 6 are arranged on the portal system 1 in the longitudinal direction; in the specific application process, the number of the first rails 6 can also be set to multiple, and the multiple first rails 6 are connected to the fixing rods 5 at intervals in the transverse direction, that is, Figure 3 As shown;

[0053] The hydraulic extrusion clamp 4 is connected to the first rail 6 through the sliding assembly 7, and the sliding assembly 7 can slide longitudinally on the first rail 6, thereby realizing the longitudinal displacement of the hydraulic extrusion clamp 4; wherein the sliding assembly 7 can be directly set as a longitudinal sliding trolley, and the hydraulic extrusion clamp 4 can be hoisted on the sliding assembly 7 through the lifting rope 8, that is, Figure 4 shown.

[0054] refer to Figure 5 In the second embodiment, the implementation of the mechanical mechanism is basically the same as that of the first embodiment, except that:

[0056] The hydraulic extrusion clamp 4 is hoisted on the first lifting device 702 through the lifting rope 8, so that the hydraulic extrusion clamp 4 can be lifted vertically while being longitudinally displaced; wherein, the first lifting device 702 can be a winch.

[0057] refer to Figure 6 , Figure 7 In the third embodiment, the implementation of the mechanical mechanism is basically the same as that of the first embodiment, except that:

[0058] The sliding assembly 7 includes a first sliding member 701 that is slidably matched with the first track 6, and a second track 703 that is arranged on the first sliding member 701 in a transverse direction;

[0059] The hydraulic extrusion clamp 4 is connected to the second rail 703 through the first connecting assembly 9, so that the hydraulic extrusion clamp 4 can be displaced in the longitudinal direction and in the transverse direction at the same time;

[0060] The first connecting component 9 may be a connecting block fixed on the second track 703, or a second sliding member slidably connected to the second track 703, and the hydraulic extrusion clamp 4 may be suspended on the first connecting component 9 by a suspension rope 8. With the extension or folding of the second track 703, or with the sliding of the first connecting component 9 on the second track 703, the lateral displacement of the hydraulic extrusion clamp 4 can be achieved.

The hydraulic extrusion clamp 4 is connected to the sliding rail 7032 through a first connecting assembly 9. As the sliding rail 7032 slides transversely on the fixed rail 7031, the hydraulic extrusion clamp 4 can be displaced in the transverse direction. It is worth noting that a coaxial telescopic rod can also be used as the second track 703 in application.

[0063] refer to Figure 8 , Fig. 9 The second track 703 is a foldable track structure, and at this time, the second track 703 includes a first track body 7034 and a second track body 7035. The first end of the first track body 7034 is hinged to the bottom of the first sliding member 701 through a first hinge 7036, and the second track body 7035 is hinged to the second end of the first track body 7034 through a second hinge 7037. The hydraulic extrusion clamp 4 is connected to the second track body 7035 through a first connecting component 9, that is, the second track 703 is foldable as a whole, and during the folding process of the second track 703, the hydraulic extrusion clamp 4 can be displaced in the horizontal and vertical directions.

[0067] refer to Fig.11In the fifth embodiment, the mechanical mechanism includes telescopic frames 10 arranged on both sides of the gantry system 1, and the telescopic frames 10 can be telescoped or slid in the lateral direction on the gantry system 1, specifically:

[0068] The hydraulic extrusion clamp 4 is connected to the telescopic frame 10 through a second connecting component. The second connecting component can directly adopt a connecting block, and then as the telescopic frame 10 is extended or slid on the gantry system 1, the hydraulic extrusion clamp 4 can be driven to move in the lateral direction.

[0069] In the sixth embodiment, the embodiment of the mechanical mechanism is substantially the same as that of the fifth embodiment, except that:

[0070] The second connection assembly is composed of a connection block and a third lifting device connected below the connection block, or the third lifting device is directly used as the second connection assembly;

[0071] The hydraulic extrusion clamp 4 is hoisted on the third hoisting device through the hoisting rope 8, so that the hydraulic extrusion clamp 4 can be lifted vertically while being displaced horizontally.

[0072] refer to Fig.12 In the seventh embodiment, the implementation of the mechanical mechanism is basically the same as that of the fifth embodiment, except that:

[0075] The third connection component is composed of a connection block and a lifting device connected below the connection block, or the lifting device is directly used as the third connection component;

[0076] The hydraulic extrusion clamp 4 is hoisted on the hoisting device through the hoisting rope 8, so that the hydraulic extrusion clamp 4 can be lifted vertically while being able to achieve longitudinal and lateral displacement.

[0077] It is worth noting that the mechanical mechanism for realizing the longitudinal, transverse and / or vertical displacement of the hydraulic extrusion pliers 4 may also adopt other implementations, as long as it realizes the longitudinal, transverse and / or vertical displacement of the hydraulic extrusion pliers 4 .

[0078] In the specific implementation process, the hydraulic extrusion clamp 4 needs to cooperate with the hydraulic station 12 and the hydraulic system accessories 13 to work, that is, Fig.13 As shown. In this embodiment, the hydraulic extrusion clamp 4 located on one side of the gantry system 1 uses a set of hydraulic stations, and the hydraulic extrusion clamp 4 located on the other side of the gantry system 1 uses another set of hydraulic stations. Preferably, the hydraulic extrusion clamps 4 located on both sides of the gantry system 1 use a set of hydraulic stations together, that is, the steel sleeves on both sides of the gantry system 1 can be docked at the same time through a set of hydraulic stations, thereby saving time and resources. As for the specific implementation of the hydraulic station, the liquid system and the hydraulic extrusion clamp 4, they are conventional technical means in the field, so they will not be described in detail in this embodiment.
