In the above technical solution, by providing the traction member 124, the relative rotation between the main gripping arm 122 and the main boom 121 can be achieved, so as to improve the flexibility of the main boom 120 during the arch erecting operation.

Specifically, the traction member 124 is mainly configured to rotate the main gripping arm 122 relative to the main arm 121 in a pitch plane. Of course, if desired, the position or direction of the pulling member 124 may be adjusted such that the pulling member 124 may rotate the main gripping arm 122 in a horizontal plane relative to the main arm 121.

Referring to fig. 2, the traction member 124 includes an ear plate 1241 and a telescopic cylinder 1242, the ear plate 1241 is rotatably connected with the main arm 121, the ear plate 1241 is fixedly connected with the main arm 122, one end of the telescopic cylinder 1242 is connected with the main arm 121, the other end of the telescopic cylinder 1242 is rotatably connected with the ear plate 1241, and the telescopic cylinder 1242 is used for telescopic movement to drive the ear plate 1241 to rotate relative to the main arm 121.

In the above technical solution, the support 130 may play a role in supporting the main gripping arm 122. In the case that the main gripping arm 122 needs the traction member 124 to carry out traction, the supporting member 130 can reduce the load of the traction member 124, so as to avoid the overload of the traction member 124 for a long time and prevent the service life of the traction member 124 from being influenced.

Specifically, the support 130 includes a mounting block 131 and a support bar 132; wherein, the installation piece 131 is fixedly connected to the frame 110 of the arch-type trolley 100, one end of the supporting rod 132 is hinged to the installation piece 131, and the other end of the supporting rod 132 is used for supporting the main grabbing arm 122.

The support piece passes through the articulated of bracing piece 132 and installation piece 131, and when bracing piece 132 was not supported main arm 122, bracing piece 132 can take place to fall under self gravity effect to dodge the upside space of installation piece 131, avoid producing the interference. In addition, the supporting rod 132 can be abutted against one end of the main grabbing arm 122 for position adjustment, so that the main grabbing arms 122 located at different positions can be abutted conveniently, and the load of the traction piece 124 is reduced.

Of course, in other embodiments of the present utility model, the end portion of the support rod 132 connected to the mounting block 131 may be fixed, so that the position of the support rod 132 abutting against one end of the main gripping arm 122 is relatively fixed, so as to ensure that the main gripping arm 122 is stable when receiving the abutting supporting effect.

In this embodiment, the mounting block 131 is configured to be coupled to the tail portion of the frame 110. Conventionally, the grip 123 and the main grip arm 122 are typically located at the rear of the frame 110 when they are stowed. The mounting block 131 is arranged at one end close to the grip 123, so that on one hand, the support position of the main grip arm 122 can be close to the grip 123, and the load on the frame 110 can be reduced by utilizing the lever principle; on the other hand, the extension length of the support bar 132 can be reduced, thereby improving the space utilization of the upper side of the frame 110.

Of course, in other embodiments of the present utility model, the mounting block 131 may be disposed at other positions such as the middle of the frame 110, but the size and strength characteristics of the mounting block 131 need to be calculated and checked.

Referring to fig. 5 and 6, the main grip arm 122 is provided with a fixed block 1221, one end of the support bar 132 is hinged to the mounting block 131, the other end of the support bar 132 is detachably connected to the fixed block 1221, and the support bar 132 and the fixed block 1221 are detachably connected, thereby improving convenience of operation.

The fixed block 1221 and the main gripping arm 122 may be integrally formed or welded.

Of course, in other embodiments of the present utility model, the main gripping arm 122 may be directly supported by the support bar 132 without the fixing block 1221.

Referring to fig. 6, the fixed block 1221 is concave, the fixed block 1221 is relatively provided with a first inner groove 1222 and a first outer abutting surface 1223, the supporting rod 132 is connected to the first inner groove 1222 through the latch 133, and the first outer abutting surface 1223 contacts the main gripping arm 122.

In the above technical solution, on one hand, the overall structural strength of the supporting rod 132 and the fixed block 1221 can be improved, so as to avoid the supporting rod 132 from being bent by the main gripping arm 122; on the other hand, the first inner groove 1222 may have a certain limiting effect on the supporting rod 132, so as to prevent the supporting rod 132 from easily disengaging from the first inner groove 1222.

And, when the bolt 133 is used to connect the first inner groove 1222 and the supporting rod 132, the supporting rod 132 and the first inner groove 1222 are provided with a through hole for accommodating the bolt 133, and the bolt 133 is used to connect the first inner groove 1222 and the supporting rod 132, so that the dismounting process can be faster.

Of course, in other embodiments of the present utility model, the support rod 132 and the first inner groove 1222 may be removable by a threaded connection.

Referring to fig. 6, the support bar 132 has a U-shaped cross section. The cross section of the support rod 132 may be understood as a cross section perpendicular to the axial extension direction of the support rod 132, and by defining the cross section dimension of the support rod 132, the support rod 132 may have better structural strength and rigidity while having less material.

Referring to fig. 6, the mounting block 131 is also concave, the mounting block 131 is relatively provided with a second inner groove 1311 and a second outer abutting surface 1312, the second outer abutting surface 1312 is connected to the frame 110, and the supporting rod 132 is hinged to the second inner groove 1311.

By providing the second inner groove 1311, when the support rod 132 does not support the fixed block 1221 and the support block naturally falls under the influence of gravity, the support block can move in the second inner groove 1311, and the support block and the second inner groove 1311 are not mutually infected, so that the upper side of the mounting block 131 is avoided.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
