Description

Technical Field

[0001] This utility model belongs to the field of crane installation technology, and in particular relates to a handling and conveying device for crane installation. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. Also known as an overhead crane, gantry crane, or hoist, a crane generally consists of a crane beam, a trolley traveling mechanism, a lifting trolley, a trolley traveling mechanism, a hoisting mechanism, hoisting attachments, and a control system. Because cranes need to lift heavy goods, they are generally quite heavy, and their various components are also relatively heavy. Currently, large crane components are transported using trolleys. Another crane lifts the crane components onto a mobile trolley, which then moves them to the crane assembly point. Another lifting device then unloads the crane components from the trolley. However, existing trolleys have flat roofs, and crane components may shift during transport, causing them to fall off. Current crane transport mechanisms lack clamping and securing mechanisms for crane components, and require the cooperation of multiple cranes and operators to move them. Therefore, the current method of transporting crane components is inconvenient, increasing labor costs and reducing production efficiency. Utility Model Content

[0003] This utility model aims to solve the problem of a handling and conveying device for crane installation, including a movable trolley. The trolley includes a horizontally arranged trolley frame, and a vertically arranged support leg is fixed to the bottom of the trolley frame. The support leg is rotatably equipped with a traveling wheel. The left end of the trolley frame is provided with a handrail push rod. The trolley can also be configured to drive the traveling wheel through a traveling motor, which is existing technology and will not be described here. The trolley is equipped with a horizontally positioned support platform above it. A lifting mechanism for adjusting the height of the support platform is located between the support platform and the trolley. The lifting mechanism includes a vertically positioned electric actuator, the bottom of which is fixed to the top of the trolley, and the top of which is fixed to the bottom of the support platform. It also includes a guide mechanism positioned between the support platform and the trolley. The guide mechanism includes four vertically positioned outer guide tubes, the bottom of which is fixed to the trolley. A vertically positioned inner guide tube is fitted onto the upper end of each outer guide tube, and the top of the inner guide tube is fixed to the bottom of the support platform. When the electric actuator is powered via a cable, its free end extends and pushes the support platform vertically upwards, allowing the height of the support platform to be adjusted as needed. A horizontally positioned support frame is located above the support platform. A support plate, which provides support, is positioned between the support frame and the support platform. Several sets of spaced support rollers are mounted on the support frame. Each support roller set consists of several evenly spaced support rollers, and each support roller is rotatably mounted on the support frame. A vertically positioned left baffle and a right baffle are positioned between two adjacent support roller sets. A horizontally positioned guide groove is provided on the support platform below the left baffle, and a slider is slidably connected within the guide groove. The bottom end of the left baffle is fixed to the slider, and the upper end of the left baffle extends upward to form a support roller set. A horizontally positioned lead screw is rotatably mounted between the two support plates. A lead screw motor, which is connected to the lead screw drive, is mounted on the support plate at one end of the lead screw. The lead screw motor is connected to a power supply and a PLC controller via a cable. When the lead screw motor is started, it drives the lead screw to rotate. The upper end of the left baffle is threaded onto a lead screw, and the lower end of the right baffle is slidably mounted in a guide groove via a slider. A horizontally arranged slide rod is fixed on the right-side support plate. The right baffle is slidably connected to the lead screw and the slide rod. A spring is installed on the slide rod between the right baffle and the support plate. The lead screw motor drives the lead screw to rotate clockwise, pushing the left baffle to the right. The lead screw motor also drives the lead screw to rotate counterclockwise, pushing the left baffle to the left. A lifting mechanism for lifting heavy objects is located at the top of the trolley. The lifting mechanism includes a vertically arranged support column, which is rotatably mounted on the trolley via a rotary mechanism. A horizontally arranged support beam is fixed to the top of the support column, and a horizontally arranged traveling rail is fixed to the bottom of the support beam. An electric hoist for lifting heavy objects is mounted on the traveling rail.

[0004] Preferably, the rotary mechanism includes a bearing seat fixed to the top of the trolley, a support column rotatably mounted on the trolley, and a motor support fixed to the top of the trolley. The motor support is equipped with a rotary motor, which is connected to the support column via a gear set.

[0005] The above scheme has the following advantages:

[0006] The support roller assembly on the support frame and the left baffle on the lead screw are driven by the lead screw motor to rotate. The left baffle can push the crane parts placed on the support roller assembly to the right baffle. The left and right baffles work together to clamp and fix the crane parts, preventing them from shifting and falling when the crane parts are transported by the trolley. The lifting structure can adjust the height of the support platform according to actual needs, making it easier for workers to load and unload crane parts. The lifting mechanism can lift the crane parts with an electric hoist, saving manpower and improving work efficiency. Attached Figure Description

[0013] Usage process:

[0014] In use, the trolley 1 is first moved to the location of the crane accessory to be lifted. Then, the position of the left baffle 53 is adjusted, moving it to the left end of the lead screw 5. The lead screw motor 52 drives the lead screw 5 to rotate counterclockwise, pushing the left baffle 53 to the left. Then, the crane accessory is lifted onto the support roller group 41 between the left baffle 53 and the right baffle 54 using the hook on the electric hoist 63. The lead screw motor 52 is started again, driving the lead screw 5 to rotate clockwise, pushing the left baffle 53 to the right. The left baffle 53 and the right baffle 54 work together to clamp and fix the crane accessory, preventing it from shifting and falling while the trolley 1 is transporting it. After the trolley 1 has moved to the designated position, the lead screw motor 52 is started again, pushing the left baffle 53 away from the crane accessory. The crane accessory can then be unloaded using the electric hoist.
