In the present embodiment, the longitudinal movement structure is attached to the front portion (i.e., the head portion) of the vehicle body 32, so the longitudinal movement structure and the lateral movement structure move with the vehicle body 32, and the actions of the longitudinal movement structure and the lateral movement structure can be within the sight of the operator, helping the operator to control the placement of the precast block 33. In addition, since the prefabricated section 33 needs to be installed at the edge of the bridge, in order to ensure the safety of the operator, the vehicle body needs to be away from the edge of the bridge, so the distance of the first sliding block 2 moving along the longitudinal direction is long, and the difference between the actual position of the prefabricated section 33 and the preset position is easy to generate. In order to ensure the accurate placement of the prefabricated section 33, the position of the first sliding block 2 needs to be within the visual range of the operator, so as to facilitate the first sliding block 2 to control the longitudinal movement path of the first sliding block 2, and therefore, the longitudinal movement structure is arranged above the transverse movement structure. And the horizontal length of second slider 5 can be greater than the interval in the outside that two first slide rails 1 carried on the back mutually, and the position of second slider 5 also can be in operating personnel's visual scope, guarantees the accurate position that falls of prefabricated section 33.

Of course, the vehicle body 32 is a vehicle commonly found in the art, such as a vehicle body of a forklift truck, and the description thereof is omitted in this embodiment. The operator can control the first electric push rod 3, the second electric push rod 6, the third electric push rod 14, the jacking hydraulic cylinder, the push-pull hydraulic cylinder 19, and the like in the vehicle body 32. In addition, as shown in FIG. 1, preform block 33 includes a bottom plate 35 and two risers 34, with the two risers 34 disposed on top of bottom plate 35 and spaced longitudinally apart.

In the embodiment, when the first sliding block 2 is driven to move along the first sliding rail 1 by the first electric push rod 3, the second sliding block 5 can move along the longitudinal direction; when the second sliding block 5 is driven to move along the second sliding rail 4 by the second electric push rod 6, the second sliding block 5 can move along the transverse direction, so that the position of the second sliding block 5 is adjusted. As long as bridge deck subsidiary facility precast block 33 (hereinafter referred to as precast block 33) is connected with second slider 5, and vehicle body 32 is driven to the preset position, the position of precast block 33 can be adjusted, so that accurate alignment installation of precast block 33 is facilitated, and construction efficiency is improved.

In this embodiment, the prefabricated section 33 and the second sliding block 5 can be connected together by some connecting means. For example, a plurality of arc-shaped lifting lugs are provided at the bottom of the second slider 5, and a lifting rope of the precast block 33 is hung and pulled by the lifting lugs. For another example, a lifting hook is provided at the bottom of the second slider 5, and a rope on which the precast block 33 is hung by the lifting hook. For another example, a plurality of pairs of L-shaped steel bar hooks are provided at the bottom of the second slider 5, and the prefabricated block 33 may be placed at the bent section of the L-shaped steel bar hook. Of course, other ways of connecting the prefabricated section 33 with the second sliding block 5 will be apparent to those skilled in the art, and the embodiment will not be described in detail. It should be noted that the longitudinal direction refers to the longitudinal direction of the vehicle body 32, or the direction in which the vehicle body 32 advances; the lateral direction refers to the width direction of the vehicle body 32. The first electric push rod 3 and the second electric push rod 6 are electric push rods common in the art, and the description of the invention is omitted.

As shown in fig. 1 to 2, in some embodiments, the opposite inner sides of the two first sliding rails 1 are provided with first rail grooves 7. The first slider 2 is mounted in the two first rail grooves 7 at both lateral ends thereof, respectively. The bottom of the lateral end of the first slider 2 is in contact with the side wall of the first rail groove 7, and the bottom of the lateral end of the first slider 2 and/or the side wall of the first rail groove 7 is provided with a frosted surface.

In the present embodiment, the openings of the two first rail grooves 7 are opposite, and the bottom wall of the first rail groove 7 is vertical, and the two side walls are vertically opposite. The width of the first track groove 7 (i.e., the interval between the two side walls) is greater than the thickness of the first slider 2. Both lateral ends of the first slider 2 are movably inserted into the two first rail grooves 7, and the first slider 2 moves on the lower side wall of the first rail groove 7. The two ends of the first track can be provided with a baffle plate for preventing the first sliding block 2 from sliding off. Preferably, the first sliding rail 1 may be made of channel steel or i-steel.

The weight of the precast block 33 is heavy, so the inertia of the precast block 33 is large. When the longitudinal movement of the precast block 33 is completed, the precast block 33 keeps moving trend under inertia, and pulls the first slide block 2 to keep moving trend as well. This may cause a certain degree of damage to the first electric putter 3 and also may not facilitate accurate placement of the preform block 33. In the present embodiment, since at least one of the bottom of the lateral end of the first slider 2 and the side wall of the first track groove 7 is provided with a frosted surface, there is a large friction between the first slider 2 and the first track groove 7 when moving in the two. When the first electric push rod 3 stops extending, the large friction force between the first sliding block 2 and the first track groove 7 can effectively restrain the moving inertia of the precast block 33 and the first sliding block 2, so that the precast block 33 and the first sliding block 2 are static and stable as soon as possible.

In a preferred embodiment of the above embodiment, the bottom of the first sliding block 2 extends out of the bottom side of the first sliding rail 1, so as to facilitate the direct connection between the second sliding rail 4 and the bottom of the first sliding block 2, and keep a certain distance between the second sliding rail 4 and the first sliding rail 1. And the horizontal both sides of the bottom of first slider 2 and have the interval between first slide rail 1 to avoid first slider 2 card to die between two first slide rails 1.

As shown in fig. 1 to 4, in some embodiments, the opposite inner sides of the two second slide rails 4 are provided with second rail grooves 8; both longitudinal ends of the second slider 5 are respectively installed in the two second rail grooves 8. The bottom of the longitudinal end of the second slider 5 is in contact with the side wall of the second rail groove 8, and the bottom of the longitudinal end of the second slider 5 and/or the side wall of the second rail groove 8 is provided with a frosted surface.

In the present embodiment, the openings of the two second rail grooves 8 are opposite, and the bottom wall of the second rail groove 8 is vertical, and the two side walls are vertically opposite. The width of the second track groove 8 (i.e., the interval between the two side walls) is greater than the thickness of the second slider 5. The longitudinal ends of the second slider 5 are movably inserted into the two second track grooves 8, and the second slider 5 moves on the lower side wall of the second track groove 8. The two ends of the second track can be provided with baffles for limiting the second sliding block 5 to slide down. Preferably, the second slide rail 4 may be made of channel steel or i-steel.

In this embodiment, at least one of the bottom of the longitudinal end of the second sliding block 5 and the side wall of the second track groove 8 is provided with a frosted surface, so that when the second sliding block 5 moves in the second track groove 8, there is a large friction force between the two, and the friction force can effectively suppress the moving inertia of the precast block 33 and the second sliding block 5, so that the precast block 33 and the second sliding block 5 are stationary and stable as soon as possible.

In a preferred embodiment of the above embodiment, the bottom of the second sliding block 5 extends out of the bottom side of the second sliding rail 4, so as to facilitate the direct connection between the rotating cylinder 12 and the bottom of the second sliding block 5, and keep a certain distance between the rotating cylinder 12 and the second sliding rail 4. And the longitudinal two sides of the bottom of the second sliding block 5 are spaced from the two second sliding rails 4, so that the second sliding block 5 is prevented from being clamped between the two second sliding rails 4.

As shown in fig. 1, in some embodiments, a connecting bar 9 (i.e., a bar-shaped connecting member) is connected between the two first sliding rails 1, one end of the first electric push rod 3 is hinged to the connecting bar 9, and the other end of the first electric push rod 3 is hinged to the first sliding block 2.

In this embodiment, the connecting strip 9 can connect the two first slide rails 1, so that a stable distance is maintained between the two first slide rails 1, and the two first slide rails 1 are also prevented from shaking. The main body section of the first electric push rod 3 can be hinged with the connecting strip 9, and the telescopic section of the first electric push rod 3 can be hinged with the first sliding block 2. When the first electric push rod 3 extends or shortens, the first sliding block 2 moves forwards or backwards relative to the connecting strip 9, so that the hoisting frame is driven to move.

In a preferred embodiment of the above embodiment, the bottom of the connecting bar 9 is provided with a pair of laterally spaced lugs, which are provided with pin holes; the tail end of the main body section of the first electric push rod 3 is provided with a hinge block, and the hinge block is provided with a pin hole; the hinge block is positioned between the two ear plates and is hinged with the ear plates through a pin shaft.

As shown in fig. 1 to 4, in some embodiments, a first mounting groove 10 is provided between the first sliding blocks 2, and the length of the first mounting groove 10 extends in the longitudinal direction; first electric putter 3 installs in first mounting groove 10, and first electric putter 3's one end is articulated with connecting strip 9, and first electric putter 3's the other end is articulated with the lateral wall of first mounting groove 10.

In the present embodiment, the first mounting groove 10 is located below the connection bar 9. The first electric push rod 3 is arranged in the first mounting groove 10; that is, the first electric putter 3 is installed in a longitudinal direction. When the first electric push rod 3 extends, the first slide block 2 can be driven to move forwards along the longitudinal direction. The first electric putter 3 is received in the first mounting groove 10, simplifying the longitudinal movement structure and reducing the weight of the longitudinal movement structure.

As shown in fig. 1 to 4, in some embodiments, a second mounting groove 11 is provided between the second sliding blocks 5, and the length of the second mounting groove 11 extends in the transverse direction; the second electric push rod 6 is arranged in the second mounting groove 11, one end of the second electric push rod 6 is hinged with the bottom of the first sliding block 2, and the other end of the second electric push rod 6 is hinged with the side wall of the second mounting groove 11.

In the present embodiment, the second installation groove 11 is located below the first installation groove 10. The second electric push rod 6 is arranged in the second mounting groove 11; that is, the second electric putter 6 is installed in a lateral direction. When the first electric push rod 3 extends, the first slide block 2 can be driven to move leftwards or rightwards along the transverse direction.

In the present embodiment, the second electric push rod 6 is received in the second mounting groove 11, so that the second slide rail 4 can be directly connected with the first slide block 2, and the distance between the first slide block 2 and the second slide block 5 is also shortened. Namely, the traverse structure is more simplified. And first slider 2 intensity is great, and is more stable after the atress, so second electric putter 6 is connected with first slider 2 and can make second electric putter 6's operating condition more stable. On the contrary, if the connecting members are disposed on the two second slide rails 4, the connecting members are limited by the narrow space between the first slide block 2 and the second slide block 5, and the thickness of the connecting members is inevitably small, so that the stress is poor. If the second electric push rod 6 is hinged to the link, the link is more easily deformed. Similar to the above preferred embodiment, the bottom of the first sliding block 2 may be provided with a pair of longitudinally spaced lugs, and the end of the main body section of the second electric push rod 6 is provided with a hinge block, which is located between the two lugs and is pin-connected with the lugs.

In some embodiments, the lifting device further comprises a swivel structure located below the traversing structure, as shown in figure 5. The rotating structure comprises a rotating cylinder 12, the top of the rotating cylinder 12 is connected to the bottom of the second sliding block 5, and the bottom of the rotating cylinder 12 is rotatably connected with a bearing part 13. The side of the drum 12 is connected to a carrier 13 by a third electric ram 14. The bearing part 13 is used for connecting a hoisting object.

In this embodiment, when the third electric pushing rod 14 extends or shortens, the supporting member 13 can be driven to horizontally rotate by a certain angle, so that the supporting member 13 can drive the prefabricated section 33 to rotate by a certain angle, thereby implementing accurate alignment installation of the prefabricated section 33.

In the present embodiment, the drum 12 is a cylindrical structure, i.e., the drum 12 includes a bottom wall and a side wall that is curled cylindrically. The cylindrical structure can reduce the weight of the drum 12. Of course, multiple stiffeners may be provided within the bowl 12 to strengthen the internal structure. The top of the drum 12 may be provided with a flange to facilitate connection with the second slide 5.

In this embodiment, the top of the rotating cylinder 12 can be connected to the bottom of the second slider 5 by bolts or rivets, or can be welded to the bottom of the second slider 5. There are various types of rotational connections between the drum 12 and the support member 13. For example, the bottom of the drum 12 can be pivotally connected to the hoist frame by a pin. For another example, a rotating member is provided at the bottom of the drum 12, one end of the rotating member is connected to the bottom of the drum 12, the other end is cylindrical, and the diameter of the cylindrical end is larger than the diameter of the other portion; the top of hoisting frame is equipped with the recess, and this recess is used for the adaptation to rotate the piece for hoisting frame can rotate through the cooperation that rotates piece and recess. As another example, the bottom of the drum 12 and the top of the sling rack are connected by a pivoting support.

In this embodiment, the bearing member 13 may be a frame structure, a solid plate, or a rod structure.
