Description

Technical Field

[0001] The present application relates to the technical field of construction engineering equipment, and in particular to a mobile hoisting trolley. Background Art

[0002] During the construction of an energy-storage power station, concrete pouring is required for the dam's slabs to form the dam slope. Typically, this slab pouring is performed on a slope, where slurry needs to be spread. In related technologies, this is typically accomplished by using a winch fixed to the top of the dam slope to pull a platform carrying workers up and down the slope.

[0003] Because the panels are typically quite wide, pouring work needs to be carried out in separate areas. After pouring in one area, the platform needs to be moved laterally to the adjacent area for pouring, and the corresponding winch also needs to be moved laterally. However, since the winch is fixed to the top of the dam slope and cannot be moved, moving the winch consumes a lot of time and manpower, affecting construction efficiency. Utility Model Content

[0004] In view of this, the purpose of the present application is to propose a mobile hoisting trolley to at least partially solve the problem of low construction efficiency caused by the inability of the hoisting device itself to move.

[0005] Based on the above-mentioned purpose, the present application provides a mobile winch trolley, comprising: a mobile base; a load-bearing bracket, which is fixedly connected to one side of the mobile base along a first direction; the first direction is perpendicular to the moving direction of the mobile base; a pitching frame, one end of the pitching frame is rotatably connected to the load-bearing bracket, and the other end of the pitching frame extends toward the side of the mobile base away from the load-bearing bracket and extends out of the mobile base; a winding roller is installed on the top of the pitching frame, and a traction rope is wrapped around the winding roller; a support frame, which is rotatably connected to the end of the pitching frame extending out of the mobile base, and the upper part of the support frame is rotatably connected to a guide wheel; the first rope end of the traction rope is led out from the winding roller and passes around the guide wheel, and the first rope end is connected to a hanging member; the bottom of the support frame is connected to a positioning component that can abut against the ground.

[0006] Optionally, at least two mutually spaced blocking bars are provided on the side of the guide wheel away from the support frame, and the blocking bars are fixedly connected to the support frame; the first rope end passes through the gap between two adjacent blocking bars, and the hanging member is located on the side of the blocking bar away from the guide wheel.

[0007] Optionally, the circumferential surface of the guide wheel is provided with a groove for accommodating the traction rope, and the axial direction of the blocking rod is parallel to the axial direction of the guide wheel.

[0008] Optionally, the positioning assembly extends along the moving direction of the movable base, and both ends of the positioning assembly are respectively provided with connecting rods that are slidably connected to the support frame.

[0009] Optionally, a first telescopic cylinder for controlling the movement of the connecting rod is provided between the connecting rod and the support frame.

[0010] Optionally, the positioning assembly includes a positioning main beam extending along the moving direction of the movable base, and a plurality of positioning spikes are provided at the bottom of the positioning main beam, and the plurality of positioning spikes are arranged at intervals along the extending direction of the positioning main beam.

[0011] Optionally, the positioning main beam is provided with a protective sleeve, and the bottom of the protective sleeve is provided with a hollow area corresponding to the positioning spike; the positioning component has a protective state and a positioning state, when the positioning component is in the protective state, the positioning main beam is away from the ground, and the positioning spike is located inside the protective sleeve; when the positioning component is in the positioning state, the bottom of the protective sleeve is in contact with the ground, and the positioning spike extends out of the protective sleeve through the hollow area and is inserted into the ground.

[0012] Optionally, a second telescopic cylinder for controlling the pitch angle of the pitch frame is provided between the mobile base and the pitch frame bracket, and a third telescopic cylinder for controlling the tilt angle of the support frame relative to the ground is provided between the support frame and the pitch frame.

[0013] Optionally, the mobile base is a crawler-type mobile base.

[0014] Optionally, a counterweight area for placing a counterweight is further provided on the top of the mobile base, and the counterweight area is located on a side of the mobile base away from the load-bearing bracket.

[0015] As can be seen from the above, the mobile hoisting trolley provided by the present application can drive the winding roller wrapped with the traction rope to move to a preset position through the mobile base, making the mobile hoisting trolley highly flexible. After the mobile base moves to the preset position, the support frame can be stably placed on the ground by controlling the pitch frame to rotate downward until the positioning assembly abuts the ground. The support frame can reliably support the traction rope released from the winding roller through the guide wheel, so that the traction rope can provide stable pulling force to the platform through the hanging member. The mobile hoisting trolley is easy to operate, which helps save working hours and manpower, thereby improving construction efficiency.

[0016] At the same time, the load-bearing bracket is located on the side of the mobile base away from the support frame. Even if the platform exerts a large downward pulling force on the traction rope, since the load-bearing bracket connected to the mobile base and the support frame supporting the traction rope are respectively located on both sides of the mobile base, it is not easy to cause the mobile base to tip over. The mobile winch trolley can provide stable and reliable pulling force for the platform, ensuring that the platform can be lifted and lowered smoothly on the slope. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In view of this, if Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application provides a mobile hoisting trolley, comprising: a mobile base 100; a load-bearing bracket 200, along a first direction (such as Figure 1 The first direction is the same as the moving direction of the mobile base 100 (eg, the X direction in FIG), the load-bearing bracket 200 is fixedly connected to one side of the mobile base 100; Figure 1 and Figure 3 The y-direction in the figure is perpendicular to the y-direction in the figure); the pitch frame 300, one end of the pitch frame 300 is rotatably connected to the load-bearing bracket 200, and the other end of the pitch frame 300 extends toward the side of the mobile base 100 away from the load-bearing bracket 200 and extends out of the mobile base 100; a winding roller 400 is installed on the top of the pitch frame 300, and a traction rope 500 is wound around the winding roller 400; a support frame 700, the support frame 700 is rotatably connected to the end of the pitch frame 300 extending out of the mobile base 100, and the upper part of the support frame 700 is rotatably connected to the guide wheel 800; the first rope end 510 of the traction rope 500 is led out from the winding roller 400 and passes around the guide wheel 800, and the first rope end 510 is connected to the hanging member 900; the bottom of the support frame 700 is connected to a positioning component 1000 that can abut against the ground 2000.

[0043] Exemplarily, the mobile base 100 may be communicatively connected to a controller, and an operator may send a movement instruction to the mobile base 100 through the controller, and the mobile base 100 may move (eg, forward, backward, or turn) according to the movement instruction.

[0044] Exemplarily, two load-bearing brackets 200 are provided and are respectively arranged on both sides of the pitch frame 300 along the moving direction of the mobile base 100. The bottom end of the load-bearing bracket 200 is fixedly connected to the mobile base 100 (for example, welded or connected by fasteners such as screws), and the upper part of the load-bearing bracket 200 is rotatably connected to the pitch frame 300 through an axis.

[0045] For example, the rotational connection method between the pitch frame 300 and the support frame 700 may be the same as the rotational connection method between the load-bearing bracket 200 and the pitch frame 300 .

[0046] For example, Figure 3 The pitch frame 300 may be a rectangular frame, and a reinforcing beam may be provided in the middle of the rectangular frame.

[0047] Exemplarily, a winding motor 600 is further installed on the top of the pitch frame 300 , and the winding motor 600 is transmission-connected to the winding roller 400 (for example, via a transmission belt or a gear set) to drive the winding roller 400 to rotate.

[0048] Exemplarily, the traction rope 500 may be a steel wire rope.

[0049] Exemplarily, the hanging component 900 may be a hook, and the first rope end 510 is tied and connected to the hanging component 900 .

[0050] Exemplarily, a wheel axle spaced apart from the support frame 700 may be provided on a side of the support frame 700 away from the pitch frame 300 , with both ends of the wheel axle fixedly connected to the support frame 700 via brackets, and the guide wheel 800 rotatably connected to the wheel axle.

[0051] by Figure 1 The structure and orientation shown are used as an example for illustration. The load-bearing bracket 200 is located on the left side of the mobile base 100, and the tilt bracket 300 extends from the left side of the mobile base 100 to the right side of the mobile base 100 and extends out of the mobile base 100. The support bracket 700 is located on the right side of the mobile base 100 and is spaced apart from the mobile base 100 along the first direction.

[0052] When the mobile hoisting trolley is needed to pull the platform, the mobile hoisting trolley is parked at the preset position at the top of the dam slope. At this time, the moving direction of the mobile base 100 is parallel to the top edge of the dam slope, the support frame 700 is close to the top edge of the dam slope, and the positioning assembly 1000 is in contact with the ground 2000 at the top of the dam slope. The hook 900 is connected to the platform, and the winding roller 400 is controlled to rotate to release more traction rope 500 so that the platform descends along the slope of the dam slope until the platform moves to the preset position on the slope. During the pouring process, the winding roller 400 can be controlled to rotate to reel in or release the traction rope 500, thereby causing the platform to rise or fall.

[0053] When the next area needs to be poured, the connecting member 900 can be separated from the platform and the tilt frame 300 can be rotated upward until the positioning assembly 1000 is separated from the ground 2000. After that, the mobile base 100 is driven to move to a new preset position and the above operation can be repeated.

[0054] The mobile hoisting trolley provided in the embodiment of the present application can drive the winding roller 400 wound with the traction rope 500 to move to a preset position through the mobile base 100, making the mobile hoisting trolley highly flexible. After the mobile base 100 moves to the preset position, the support frame 700 can be stably placed on the ground 2000 by controlling the pitch frame 300 to rotate downward until the positioning assembly 1000 contacts the ground 2000. The support frame 700 can reliably support the traction rope 500 released from the winding roller 400 through the guide wheel 800, so that the traction rope 500 can provide stable pulling force to the platform through the hanging member 900. The mobile hoisting trolley is easy to operate, helps save working hours and manpower, and thus improves construction efficiency.

[0055] At the same time, the load-bearing bracket 200 is located on the side of the mobile base 100 away from the support frame 700. Even if the downward pulling force generated by the platform on the traction rope 500 is large, since the load-bearing bracket 200 connected to the mobile base 100 and the support frame 700 supporting the traction rope 500 are respectively located on both sides of the mobile base 100, it is not easy to cause the mobile base 100 to tip over. The mobile winch trolley can provide stable and reliable pulling force for the platform, ensuring that the platform can be lifted and lowered smoothly on the slope.

[0056] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In some embodiments, at least two mutually spaced blocking bars 1100 are provided on the side of the guide wheel 800 away from the support frame 700, and the blocking bars 1100 are fixedly connected to the support frame 700; the first rope end 510 passes through the gap between the two adjacent blocking bars 1100, and the hanging member 900 is located on the side of the blocking bar 1100 away from the guide wheel 800.

[0057] Illustratively, at least one end of the blocking rod 1100 is welded and fixed to the support frame 700 via a bracket.

[0058] When the winding roller 400 reels the traction rope 500, the attachment 900 continuously moves toward the winding roller 400. In this embodiment, when the attachment 900 moves to abut against the blocking bar 1100, it is blocked by the blocking bar 1100 and stops moving. On the one hand, the blocking bar 1100 can keep the attachment 900 close to the guide wheel 800, making it convenient to use the attachment 900 when it is needed to connect to the platform next time. On the other hand, the blocking bar 1100 can also protect the guide wheel 800, preventing the attachment 900 from hitting the guide wheel 800 while moving toward the winding roller 400, thereby helping to increase the service life of the mobile hoisting trolley.

[0059] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In some embodiments, a groove 810 for accommodating the traction rope 500 is provided on the circumferential surface of the guide wheel 800 , and the axial direction of the blocking rod 1100 is parallel to the axial direction of the guide wheel 800 .

[0060] A groove 810 is provided around the guide wheel 800, and the walls of the groove 810 on both sides can provide lateral positioning for the traction rope 500. When the axial direction of the blocking bar 1100 is parallel to the axial direction of the guide wheel 800, the traction rope 500 passes through the gap between two adjacent blocking bars 1100. The blocking bars 1100 located on the upper and lower sides of the traction rope 500 can provide longitudinal positioning for the traction rope 500, preventing the traction rope 500 from dislodging from the guide wheel 800 during the retraction and extension process. This allows the mobile winch trolley to provide stable and reliable pulling force for the platform, ensuring smooth lifting and lowering of the platform.

[0061] like Figure 2 and Figure 3 In some embodiments, the positioning assembly 1000 extends along the moving direction of the mobile base 100 , and connecting rods 1005 slidably connected to the support frame 700 are respectively provided at both ends of the positioning assembly 1000 .

[0062] For example, Figure 3 Along the moving direction of the mobile base 100, the support frame 700 includes a main plate 710 located in the middle and sliding sleeves 720 located on both sides of the main plate 710. The radial cross-sectional shape of the inner hole of the sliding sleeve 720 matches the radial cross-sectional shape of the connecting rod 1005. The connecting rod 1005 is inserted into the inner hole of the sliding sleeve 720 to achieve a sliding connection between the connecting rod 1005 and the support frame 700. The ends of the pitch frame 300 can be rotatably connected to the two sliding sleeves 720.

[0063] Exemplarily, the cross-section of the connecting rod 1005 is a square.

[0064] As can be seen from the foregoing, before the mobile base 100 moves, the positioning assembly 1000 must be separated from the ground 2000. When the positioning assembly 1000 is slidably connected to the support frame 700 via the connecting rod 1005, in addition to controlling the pitch frame 300 to rotate upward to separate the positioning assembly 1000 from the ground 2000, the positioning assembly 1000 can also be separated from the ground 2000 by moving the positioning assembly 1000 upward relative to the support frame 700. This facilitates more flexible control of the mobile hoisting trolley.

[0065] like Figure 2 and Figure 3 In some embodiments, a first telescopic cylinder 1200 for controlling the movement of the connecting rod 1005 is provided between the connecting rod 1005 and the support frame 700 .

[0066] For example, the cylinder barrel of the first telescopic cylinder 1200 may be hinged to the sliding connection sleeve 720 of the support frame 700 , and the telescopic rod of the first telescopic cylinder 1200 may be hinged to the connecting rod 1005 .

[0067] Exemplarily, the first telescopic cylinder 1200 may be an electrically driven telescopic cylinder or a hydraulic oil driven telescopic cylinder.

[0068] For example, when the telescopic cylinder is driven by hydraulic oil, a container for containing the hydraulic oil and an oil pump can be installed on the top of the mobile base 100. On the one hand, this can make the structure of the mobile hoisting trolley more compact and easier to move; on the other hand, the gravity of the container, hydraulic oil, and oil pump can be used to make the mobile base 100 more stable in contact with the ground 2000, further preventing the mobile base 100 from tipping over.

[0069] When the telescopic rod of the first telescopic cylinder 1200 is extended, the positioning assembly 1000 can be driven downward until it contacts the ground 2000. When the telescopic rod of the first telescopic cylinder 1200 is shortened, the positioning assembly 1000 can be driven upward to separate the positioning assembly 1000 from the ground 2000, facilitating the movement of the mobile hoisting trolley.

[0070] like Figure 2 、 Figure 3 and Figure 6 In some embodiments, the positioning assembly 1000 includes a positioning main beam 1001 extending along the moving direction of the mobile base 100, and a plurality of positioning spikes 1002 are provided at the bottom of the positioning main beam 1001, and the plurality of positioning spikes 1002 are arranged at intervals along the extension direction of the positioning main beam 1001.

[0071] For example, the positioning spike 1002 may be in the shape of a square cone with the tip facing downward.

[0072] When the positioning assembly 1000 contacts the ground 2000, the positioning spikes 1002 can be inserted into the ground 2000, allowing the support frame 700 to be more stably placed on the ground 2000. Furthermore, the positioning main beam 1001 extends along the moving direction of the mobile base 100, which not only increases the contact area between the positioning assembly 1000 and the ground 2000, but also provides a structural foundation for installing multiple positioning spikes 1002, thereby improving the stability of the support frame 700 when placed on the ground 2000.

[0073] like Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments, the positioning main beam 1001 is provided with a protective cover 1003, and the bottom of the protective cover 1003 is provided with a hollow area 1004 corresponding to the positioning spike 1002; the positioning component 1000 has a protective state and a positioning state. When the positioning component 1000 is in the protective state, the positioning main beam 1001 is away from the ground 2000, and the positioning spike 1002 is located inside the protective cover 1003; when the positioning component 1000 is in the positioning state, the bottom of the protective cover 1003 is in contact with the ground 2000, and the positioning spike 1002 extends out of the protective cover 1003 through the hollow area 1004 and is inserted into the ground 2000.

[0074] For example, Figure 7 The radial cross-section of positioning beam 1001 can be square, and the radial cross-section of protective sleeve 1003 can be rectangular, with the short side of the rectangle matching the side length of the square, and the long side of the rectangle arranged longitudinally, so that protective sleeve 1003 can move up and down relative to positioning beam 1001. The above structure of positioning beam 1001 and protective sleeve 1003 prevents protective sleeve 1003 from rotating relative to positioning beam 1001, ensuring that hollowed-out area 1004 always corresponds to the position of positioning spike 1002.

[0075] like Figure 7When the mobile hoisting trolley is ready to move, the positioning assembly 1000 can be switched to a protective state. At this time, the positioning assembly 1000 moves upward, positioning the main beam 1001 away from the ground 2000. Under the action of its own gravity, the protective cover 1003 slides downward relative to the positioning main beam 1001 until the inner top of the protective cover 1003 is against the top of the positioning main beam 1001. After that, the protective cover 1003 and the positioning main beam 1001 rise synchronously. When the protective cover 1003 is separated from the ground 2000, the mobile hoisting trolley can move. When the positioning assembly 1000 is in a protective state, the positioning spikes 1002 are all located inside the protective cover 1003. During the movement of the mobile hoisting trolley, the positioning spikes 1002 are blocked by the protective cover 1003, so they will not cause damage to outside personnel or equipment.

[0076] like Figure 8 After the mobile hoisting trolley moves to the preset position, the positioning assembly 1000 can be switched to the positioning state. At this point, the positioning assembly 1000 moves downward, and the positioning main beam 1001 drives the protective cover 1003 gradually closer to the ground 2000. When the protective cover 1003 contacts the ground 2000, the protective cover 1003 stops moving downward, and the positioning main beam 1001 continues to move downward. As the positioning main beam 1001 moves downward relative to the protective cover 1003, the positioning spikes 1002 gradually extend through the hollow area 1004, extend from the protective cover 1003, and penetrate the ground 2000.

[0077] like Figure 1 and Figure 3 As shown, in some embodiments, a second telescopic cylinder 1300 for controlling the pitch angle of the pitch frame 300 is provided between the mobile base 100 and the pitch frame 300 bracket, and a third telescopic cylinder 1400 for controlling the tilt angle of the support frame 700 relative to the ground 2000 is provided between the support frame 700 and the pitch frame 300.

[0078] Exemplarily, the third telescopic cylinder 1400 is connected to the upper portion of the support frame 700 .

[0079] The cylinder barrel of the second telescopic cylinder 1300 can be hinged to the mobile base 100, and the telescopic rod of the second telescopic cylinder 1300 can be hinged to the pitch frame 300. The cylinder barrel of the third telescopic cylinder 1400 can be hinged to the pitch frame 300, and the telescopic rod of the third telescopic cylinder 1400 can be hinged to the support frame 700.

[0080] The structures and driving methods of the first telescopic cylinder 1200 , the second telescopic cylinder 1300 and the third telescopic cylinder 1400 may be the same, and will not be described in detail here.

[0081] When the telescopic rod of the second telescopic cylinder 1300 is extended, the tilt frame 300 rotates upward; when the telescopic rod of the second telescopic cylinder 1300 is shortened, the tilt frame 300 rotates downward. When the third telescopic cylinder 1400 is connected to the upper portion of the support frame 700 and the telescopic rod of the third telescopic cylinder 1400 is extended, the support frame 700 rotates, and the lower portion of the support frame 700 approaches the mobile base 100; when the telescopic rod of the third telescopic cylinder 1400 is shortened, the support frame 700 rotates, and the lower portion of the support frame 700 moves away from the mobile base 100.

[0082] like Figure 1 and Figure 3 As shown, in some embodiments, the mobile base 100 is a tracked mobile base.

[0083] The crawler-type mobile base can provide strong power to meet the load requirements of the mobile hoisting trolley. At the same time, the crawler-type mobile base can make the mobile hoisting trolley more stable and avoid rollover.

[0084] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, a counterweight area 101 for placing a counterweight is further provided on the top of the mobile base 100 , and the counterweight area 101 is located on a side of the mobile base 100 away from the load-bearing bracket 200 .

[0085] Since the load-bearing bracket 200 is disposed on one side of the mobile base 100, the center of gravity of the mobile base 100 may be shifted. To ensure that the mobile base 100 maintains better balance during movement and further prevent the mobile base 100 from tipping over, a counterweight may be placed on the counterweight area 101. Since the crawler-type mobile base 100 has a strong load-bearing capacity and can provide strong power, placing a counterweight on the mobile base 100 will not adversely affect the mobile base 100.
