[0034] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0035] Embodiment 1:
[0036] See Figure 1-8 , an arch beam type lifting device, including a first track 102, an arch frame 200, and a lifting trolley 300. The first track 102 is used to be installed on the foundation platforms 100 on both sides of the canyon 400. The lower sides of the two ends of the two arch frames 200 are respectively installed with traveling carriages 210, and the traveling carriages 210 on both sides are respectively used to be installed on the first tracks 102 on both sides. A plurality of lifting trolleys 300 are installed on the two arch frames 200.
[0037] Compared with the commonly used cable cranes and gantry tower cranes, because of the adoption of the arch beam form, the bearing capacity and the lifting capacity of the crane are greatly increased. The multiple lifting trolleys 300 on each arch beam type lifting device can both perform hoisting operations separately, and the trolleys on the same or different arch beam type lifting devices can also be combined to perform corresponding double trolley or multi-trolley lifting operations, meeting the hoisting requirements of multiple pouring positions and large lifting weights in the construction of dams, concrete water conservancy facilities, large-volume buildings, etc., and can well meet the operation requirements of the construction area, and are particularly suitable for large and complex construction areas.
[0038] See Figure 1, a truss structure 201 is provided on the lower side of the arch frame 200, and the structural strength of the arch frame 200 is improved by providing the truss structure. The truss structure 201 includes transverse rods and longitudinal rods. The transverse rods are connected to both ends of the lower side of the arch frame 200, and multiple longitudinal rods connect the arch frame 200 and the transverse rods. Of course, diagonal braces can be further provided between the arch frame 200 and the transverse rods. The cross braces and vertical braces are both provided under the arch frame. In order not to interfere with the position of the rack, a staggered arrangement is made to further supplement the strength of the arch frame. The arch frame, cross braces, and vertical braces are all assembled into a whole by multiple sections and are connected by welding or local flange bolts to avoid interference with components such as the track and the rack.
[0039] See Figure 4 , 5 , the walking frame 210 includes a machine base 211, roller path wheels 212, and a first motor 213. The roller path wheels 212 are rotatably installed on the lower side of the machine base 211 through a central shaft. The first motor 213 is installed on the machine base 211, and the output shaft of the first motor 213 is connected to the central shaft of one of the roller path wheels 212 for transmission; the arch frame 200 is installed on the machine base 211. Through the above structure, the arch frame 200 moves on the first track 102 through the walking frame 210.
[0040] In one of the solutions, there can be one walking frame 210, and two arch frames 200 are installed on the same walking frame 210. In another solution, see Figure 5 , a walking frame 210 is installed at both ends of each arch frame 200, and the two walking frames 210 on the same side are connected into a whole. Specifically, flange plates can be provided on the opposite sides of the two walking frames 210, and the two walking frames 210 are bolted together through the flange plates. Of course, it can also be Figure 5 the structure welded into one body through connecting rods as shown in
[0041] During specific implementation, the walking frame 210 can be welded to the lower side of the arch frame 200, or it can be installed on the lower side of the arch frame 200 by bolts as shown in Figure 5 .
[0042] See Figure 6 , 7, the hoisting trolley 300 includes a traveling seat 310, a box body 320, and a hoisting system 330. The traveling seats 310 are respectively installed on both sides of the box body 320. The traveling seats 310 on both sides are respectively on the upper side of the two arch frames 200. The hoisting system 330 is installed in the box body 320, and the hook 331 of the hoisting system 330 extends downward between the two arch frames 200; at least two traveling wheels 311 are installed on the lower side of the traveling seat 310, and the traveling wheels 311 roll and travel on the upper side of the arch frame 200. A rack 205 is installed on the lower side of the arch frame 200. A bracket 312 is installed on the outer side of the traveling seat 310. A second motor 313 is installed on the bracket 312, and a first gear 314 is installed on the output shaft of the second motor 313. The first gear 314 meshes with the rack 205 for transmission. By meshing the first gear 314 with the rack 205 on the lower side of the arch frame 200, the traveling seat 310 is limited to travel and move on the arch frame 200.
[0043] Furthermore, a second track 202 is installed on the arch frame 200, and the traveling wheels 311 roll and travel on the second track 202. Setting the second track 202 can not only improve the structural strength of the arch frame 200, but also prevent the arch frame 200 from being worn by the traveling of the traveling wheels 311, and more importantly, ensure that the traveling wheels 311 travel along the longitudinal axis of the arch frame 200 to avoid deviation faults. In this solution, the traveling wheels 311 are track wheels.
[0044] It should be noted that when the second track 202 is not provided on the arch frame 200, the traveling wheels 311 are arc-shaped wheels that cooperate with the arch frame 200.
[0045] See Figure 5 、 6 , a trolley wire 203 is also installed on the arch frame 200. An insulating board is padded between the trolley wire 203 and the arch frame 200 to ensure that the arch frame 200 is not charged. A collector 315 is installed on the traveling seat 310 or the bracket 312. A spring is provided inside the collector 315 bracket to ensure that the collector 315 always elastically maintains contact with the trolley wire 203 for conduction under various influences such as vibration, shaking, and bouncing during the operation of the device in this patent. The collector 315 is used to supply power to the hoisting system 330 and the second motor 313. Through the above structure, the power supply for the hoisting system 330 and the second motor 313 is realized. When in use, the trolley wire 203 is laid on the arch frame 200 and connected to the power supply, and the collector 315 slides along the trolley wire 203 and can conduct electricity.
[0046] Furthermore, see Figure 8, an electric control cabinet 340 is also installed inside the box body 320. The electric control cabinet 340 is electrically connected to the hub 315. The hoisting system 330 and the second motor 313 are electrically connected to the electric control cabinet 340. The electric control cabinet 340 is provided with a remote control unit inside. The hoisting system 330 and the second motor 313 are started and stopped remotely through the remote control unit. Through the above structure, the remote control of the hoisting trolley 300 and the hoisting system 330 is realized. The remote control unit is a prior art. For example, a QA600 industrial crane wireless controller is adopted. The controller includes a controller host and a remote controller.
[0047] In one of the solutions, refer to Figure 5 , a first connecting rod 204 is fixedly connected between the two arch frames 200 at the end positions.
[0048] Embodiment 2:
[0049] The difference between this embodiment and Embodiment 1 is that if the width of the canyon is large, resulting in a large width of the pouring area of the dam 401 and a large length and weight of the arch frame 200, refer to Figure 1 、 2 , two half-width arch frames 200 can be respectively arranged on the foundation platforms 100 on the left and right banks of the canyon 400 according to the above structure. After the two half-width arch frames 200 are installed in place, bolts or welding connections are made at the docking joints by personnel.
[0050] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
