For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Embodiment 1:

[0046] See also Figure 1-3A trolley self-lifting and horizontal track lifting equipment, including a longitudinal track platform 3, a first track 6 is fixed on the top of the longitudinal track platform 3, a main frame structure 8 is supported on the top of the first track 6 through a first walking trolley 7, a lifting trolley 9 is supported on the top of the main frame structure 8 through a second track 806, and a winch lifting device 10 is supported on the lifting trolley 9 through a third track 901; the first lifting platform 4 and the second lifting platform 5 are respectively installed on the vertical main beams 801 of the main frame structure 8 on both sides through a gear rack lifting mechanism, and the first lifting platform 4 and the second lifting platform 5 cooperate with the lifting trolley 9 and lift it. By adopting the above-mentioned lifting equipment, the main frame structure 8 can effectively reduce the weight of the entire lifting equipment, while ensuring the structural strength of the entire lifting equipment, and can simultaneously arrange multiple lifting trolleys 9 on the main frame structure 8 to perform lifting operations separately, which greatly improves the lifting capacity while simplifying the structure, and improves the construction and pouring efficiency.

[0047] Furthermore, the main frame structure 8 includes a vertical main beam 801 fixed on the top of the first walking trolley 7, a horizontal main beam 805 is fixed between the tops of the two groups of vertical main beams 801 on the same side, an arch beam 803 is fixed to the bottom end of the horizontal main beam 805 through multiple groups of symmetrically arranged vertical rods 804, and the bottom end of the arch beam 803 is fixed between the lower parts of the vertical main beams 801; a rack 802 is arranged on the inner side wall of the vertical main beam 801; a second track 806 is fixed to the top of the horizontal main beam 805; and a lower cross beam 807 is fixed between the lower parts of the horizontal main beams 805. By adopting the above-mentioned main frame structure 8 and the structural form of the arch beam 803, the bearing capacity of the entire main frame structure 8 is effectively improved, and its structural strength and stability are guaranteed; in addition, this main frame structure 8 can effectively reduce the main weight of the entire lifting equipment.

[0048] Furthermore, the horizontal main beam 805 and the corresponding vertical main beam 801 are arranged at an angle less than a right angle, so that the pair of vertical main beams 801 across form a structural form with a large spacing at the upper end and a small spacing at the lower end. The reason for adopting the above-mentioned arrangement structure is that when the device is subjected to a large weight load, the horizontal main beam and the arch beam can be slightly bent downward, so that the pair of vertical main beams at both ends become substantially the same distance between the upper and lower ends. On the one hand, under the same structural form, it can have a greater load-bearing capacity; on the other hand, under a large load condition, the vertical main beam maintains a vertical operating state, which is more conducive to the stability of the overall structure. In addition, in order to adapt to this adjustment, the surface of the first track 6 is an arc surface, and the contact surface between the first track wheel 703 and the first track 6 is also an arc, thereby ensuring that during the change of the inclination angle of the vertical main beam 801, the first walking trolley 7 and the first track 6 can always maintain good contact and a reliable operating state.

[0049] Furthermore, the first walking trolley 7 includes a first trolley body 701, a first rail wheel 703 is installed at the bottom of the first trolley body 701, the first rail wheel 703 cooperates with the first rail 6, and the first rail wheel 703 is connected to a first motor 702 for driving the rotation thereof. The first walking trolley 7 can be used to drive the entire main frame structure 8 to walk along the first rail 6, thereby increasing the hoisting and placement range of the items and enhancing the flexibility and convenience of use.

[0050] Furthermore, a main platform 2 higher than the longitudinal track platform 3 is provided on the side of the longitudinal track platform 3, and a docking track 1 for docking and supporting the hoisting trolley 9 is provided on the top of the main platform 2; the docking track 1 and the second track 806 are arranged in the same spacing and the same model. In this way, it is ensured that the trolley on the main platform 2 can dock and move to the first lifting platform 4 and the second lifting platform 5.

[0051] Furthermore, grooves are provided between the docking rails 1 to form a vertical space to accommodate the movable pulley 1004 and the hook 1005 of the hoisting lifting device 10. This ensures that the hoisting trolley 9 can drive the hoisting lifting device 10 to move on the main platform 2.

[0052] Furthermore, the first lifting platform 4 and the second lifting platform 5 adopt the same structure, wherein the second lifting platform 5 includes a lifting trolley body 501, and a motor-driven gear 506 is rotatably installed on the side of the lifting trolley body 501 through a connecting seat 505, and the gear 506 is meshed with the rack 802 for transmission, thereby forming a gear rack lifting mechanism; a diagonal brace 503 is arranged at the bottom of the lifting trolley body 501, and the end of the diagonal brace 503 rolls in contact with the outside of the vertical main beam 801 through a stop wheel 504; a lifting rail 502 is fixed on the top of the lifting trolley body 501, and the lifting rail 502 and the second rail 806 are arranged in the same spacing and the same model. The above-mentioned first lifting platform 4 and second lifting platform 5 can be used to assist in the installation and lifting of the lifting trolley 9, thereby replacing the traditional lifting installation method, improving the installation efficiency and convenience of the lifting trolley 9, and also facilitating the maintenance of the lifting trolley 9 and the increase and decrease of the number of trolleys during operation, and it is very flexible and convenient to use. During the working process, the gear 506 is driven by the motor, and the gear 506 is meshed with the rack 802 for transmission, thereby driving the entire first lifting platform 4 or the second lifting platform 5 to rise and fall along the vertical main beam. An inclined support and a stop wheel set at the end of the lifting platform are also arranged at the bottom of the lifting platform. The stop wheel contacts the outer side of the vertical main beam and rolls up and down on it. In this way, the lifting platform is driven to move up and down on the vertical main beam through the joint action of the star teeth and the stop wheel.

[0053] Furthermore, after the first lifting platform 4 is lowered to the lowest position, the lifting track 502 can be aligned with the docking track 1. This ensures that after the lifting trolley on the main platform drives onto the lifting platform, the lifting platform is lifted to the same height as the horizontal main beam, and then the lifting trolley can move onto the track of the horizontal main beam.

[0054] Furthermore, the hoisting trolley 9 includes a hoisting trolley body 902, a running wheel 903 is installed at the bottom of the hoisting trolley body 902, the running wheel 903 cooperates with the second track 806, the running wheel 903 is connected to the second motor 905 for driving its rotation, and a third track 901 is installed at the bottom of the hoisting trolley body 902; a limiting wheel 904 is arranged on the outer side of the hoisting trolley body 902, and the limiting wheel 904 contacts and cooperates with the outer side wall of the transverse main beam 805. The above-mentioned hoisting trolley 9 can drive the entire hoisting and lifting device 10 to move along the second track 806. In addition to driving the running wheel on the second track 806 by the second motor 905, the hoisting trolley 9 also abuts against the outer edge of the transverse main beam through the limiting wheel 904 connected to the running wheel shaft, and moves synchronously with the running wheel of the hoisting trolley, thereby ensuring that there is no risk of deflection and derailment during the operation of the hoisting trolley.

[0055] Further, the hoisting device 10 includes a hoisting winch 1001, which is supported on the top of the third track 901. A hoisting motor 1002 is installed on the hoisting winch 1001, which drives a hoisting rope 1003. A movable pulley 1004 is installed on the hoisting rope 1003, and a hook 1005 is arranged on the movable pulley 1004. The hoisting device 10 is driven by the hoisting motor 1002 to retract and release the hoisting rope, and the movable pulley drives the hook to move up and down to lift the object. The running wheel of the hoisting winch moves left and right on the third track 901 arranged on the bottom plate of the hoisting trolley under the drive of its motor, so that when multiple lifting equipments cannot be displaced while running on the same track on the first track 6, the hoisting winch can be moved on the third track 901, so that the hoisting and pouring operations can be carried out more effectively and flexibly.

[0056] Furthermore, the material-retrieving method of the present lifting equipment is to run the hoisting trolley onto the lifting platforms arranged at both ends. The lifting platforms serve as extensions of the horizontal main beam and the second track. Materials are retrieved on the main platform, and then the bin is hoisted and delivered or concrete is poured. In this way, the material-retrieving platform and the main platform are arranged at the same elevation, which is convenient for material retrieving during operation.

[0057] Furthermore, the hoisting trolley 9 is also provided with a power supply control cabinet and a signal control cabinet, and a video monitoring system, a position sensor and a speed sensor are arranged as required to realize remote wireless control and precise control, thereby achieving a good remote wireless control and precise control effect.

[0058] Furthermore, the device can be provided with a driver's operating room at a suitable position on the device, or at a position on the platform that is easily observed, which is flexible and convenient.

[0059] Furthermore, the entire device is connected to the local control system or remote control system through wired or wireless communication for local or remote control; at the same time, by setting the work content on the device's own program, unmanned automatic control is achieved under the precise perception of various sensors and the joint control of programs and control elements.

[0060] Furthermore, a protective cover canopy is provided on the lifting trolley as required; the entire equipment is provided with a cable power supply or a sliding line power supply system.

[0061] Embodiment 2:

[0062] A method for operating a trolley self-elevating and horizontal track lifting device comprises the following steps:

[0063] Step 1: Arrange the lifting trolley 9:

[0064] Select a suitable number of hoisting trolleys 9 according to work needs, first lower the first lifting platform 4 to the same height as the docking track 1, drive the hoisting trolley 9 on the main platform 2 to the first lifting platform 4, and then use the first lifting platform 4 to lift the hoisting trolley 9 to the same height as the second track 806, and drive the hoisting trolley 9 to the second track 806 at the top of the horizontal main beam 805, and then follow this operation one by one to arrange multiple hoisting trolleys 9 in place;

[0065] Step 2: Single-point lifting of the lifting trolley 9:

[0066] The hoisting trolley 9 first travels to the first lifting platform 4 or the second lifting platform 5 at both ends which are at the same height as the horizontal main beam 805, and the hoisting device 10 drops the hook to hoist the object 11, driving the first traveling trolley 7, the hoisting trolley 9 or the traveling mechanism of the hoisting device 10 to move alone or in conjunction, and after reaching the hoisting point, the hook is dropped to place the hoisted object in place;

[0067] Step 3: Lifting trolley 9 linkage lifting:

[0068] Multiple lifting trolleys 9 can be used in a joint lifting manner to lift large items, or to jointly lift belt conveyors for material or concrete transportation. Joint lifting can also be performed by lifting trolleys 9 between multiple lifting equipment to achieve better lifting effects and different application scenarios.

[0069] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
