Description

Technical Field

[0001] The utility model relates to the technical field of industrial equipment, in particular to a movable escalator for industrial logistics transportation. Background Art

[0002] In the field of logistics and transportation, low-altitude operations are often required, such as loading boxes or stacking at high levels, which all require industrial escalators. To facilitate the movement and use of escalators, existing industrial escalators can often be moved, which improves practicality.

[0003] In the prior art, movable escalators used for industrial logistics transportation can also adjust the height of the workers' platform. However, when adjusting the height of the upper platform of the existing escalator, the workers are required to estimate the working height on the ground and make adjustments in advance. This method is not convenient enough and the height adjustment effect is not accurate. In addition, since the escalator is mostly a linear structure with poor stability, it is easy to topple over when receiving lateral force. For this reason, we propose a movable escalator for industrial logistics transportation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a movable escalator for industrial logistics transportation, which has an automatic lifting unit. When workers are working at a high place on the escalator, they can conveniently control the automatic lifting of the standing board through the control switch installed on the side guard bar to adjust to a suitable working height. The linkage slide bar can be lifted and lowered with the standing board, so that the side guard bar can always play a protective effect on the workers; and it has a reliable auxiliary stabilization unit. By expanding the expansion support rod outward, the width of the ground contact surface of the escalator frame can be increased, and a cross-shaped stable structure is formed in conjunction with the bottom plate, so that the escalator as a whole is more stable and the lateral tipping of the escalator is effectively avoided. It also has multiple protective components, which makes the escalator safer to use and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a movable escalator for industrial logistics transportation, comprising a bottom plate, an automatic lifting unit and an auxiliary stabilizing unit;

[0006] Bottom plate: It is a rectangular plate with a universal wheel installed at each of the four corners of the lower end, and a wheel locking device is installed inside the upper side of each universal wheel;

[0007] Automatic lifting unit: comprises a vertical support, a standing plate, a hydraulic cylinder, a linkage sliding rod, a side guard bar and a control switch, wherein the upper end of one side of the base plate is fixedly connected with four vertical supports, the four vertical supports are diagonally distributed in a rectangular shape, and three horizontal cross bars are fixedly connected at the upper end, and the upper section of each vertical support is an L-shaped structure, and the inner sliding connection of the L-shaped section of the vertical support is connected with a horizontal standing plate, and the dead corners of the standing plate are respectively stuck at the inner corners of the L-shaped section of the vertical support, and a hydraulic cylinder is installed and fixed at the upper end of the base plate and at a position vertically corresponding to the standing plate, and the telescopic end of the hydraulic cylinder faces upward and is fixedly connected to the middle position of the lower end of the standing plate, and a linkage sliding rod is fixedly connected at the four corners of the upper end of the standing plate, and the linkage sliding rod passes through the horizontal cross bar at the upper end of the vertical support, and the two maintain sliding connection, and the upper end of the linkage sliding rod is fixedly connected with three horizontal side guard bars, and a control switch is installed at the side guard bar located in the middle, and the input end of the hydraulic cylinder is electrically connected to the output end of the external power supply through the control switch;

[0008] Auxiliary stabilization unit: installed on the sides of the two long sides of the base plate.

[0009] The universal wheels on the lower side of the base plate make the escalator easy to move. The wheel locking device is used to lock the universal wheels to prevent the escalator from moving when the workers above are working. The workers climb onto the standing board through the step board and stand on the standing board to carry and stack industrial items. The side guardrails are used to prevent workers from falling from the side and can also be used for workers to hold their hands. When the workers are working, the control switch installed on the side guardrails can conveniently control the automatic lifting of the standing board to adjust to the appropriate working height. The hydraulic cylinder is used to provide the power required for the lifting of the standing board, and the linkage slide bar can be lifted and lowered with the standing board, so that the side guardrails can always protect the workers. The L-shaped section on the upper side of the vertical bracket clamps the standing board to ensure that the standing board can lift and slide smoothly. The auxiliary stabilization unit is used to improve the overall stability of the escalator.

[0010] Furthermore, the auxiliary stabilization unit comprises a support block, a vertical clamping plate, an upper clamping block and a movable shaft. A four-round support block is fixedly connected to the middle of the side of the two long sides of the bottom plate. The upper surface of the support block is a stepped structure. The vertical clamping plate is fixedly connected to the side of the support block facing outward. The stepped support block and the vertical clamping plate are clamped together to form a groove. The upper end of the vertical clamping plate is fixedly connected to an upper clamping block. The upper and lower ends of the movable shaft are rotatably connected to the upper clamping block and the support block respectively. The support block is used for the installation of the expansion support rod and supports the expansion support rod. The movable shaft enables the expansion support rod to rotate. The vertical clamping plate is used to limit the expansion support rod, so that the expansion support rod is perpendicular to the side of the bottom plate after it is fully opened outward.

[0011] Furthermore, the auxiliary stabilization unit also includes an expansion support rod, a spring and a leather foot seat. The movable shaft passes through one end of the expansion support rod. The expansion support rod is movably connected to the support block through the movable shaft. The end of the expansion support rod is clamped between the support block and the upper clamping block. The other end of the expansion support rod is installed with a leather foot seat. The movable shaft is located on the upper side of the expansion support rod and is sleeved with a spring. When the expansion support rod is fully opened outward, the spring pushes the expansion support rod to fall into the groove formed by the clamping of the support block and the vertical clamping plate. At this time, the leather foot seat moves downward a certain distance with the expansion support rod, so that it can be attached to the bottom surface. By expanding the expansion support rod outward, the width of the grounding surface of the escalator frame can be increased, and a cross-shaped stable structure is formed with the bottom plate, making the escalator more stable as a whole, and effectively preventing the escalator from tipping over sideways.

[0012] Furthermore, it also includes an oblique rod frame, a connecting frame, a supporting rod, a step plate and an anti-skid strip. An X-shaped connecting frame is fixedly connected between two adjacent vertical brackets. Two groups of oblique rod frames are fixedly connected between the vertical bracket and the bottom plate. The vertical bracket, the bottom plate and the oblique rod frame together form a right triangle structure. A supporting rod is fixedly connected between two horizontally corresponding oblique rod frames. The supporting rod is provided in three groups along the direction of the oblique rod frames. A horizontal step plate is fixedly connected to the upper end of each group of oblique rod frames, and an anti-skid strip is provided at the upper end of the step plate. The oblique rod frame is used to form a triangular stable structure with the vertical bracket and the bottom plate, and to enhance the structural strength of the escalator frame. The X-shaped connecting frame is used to enhance the connection stability between adjacent vertical brackets. The supporting rod is used for the installation of the step plate. The anti-skid strip can prevent workers from falling due to slipping when stepping on the step plate by increasing friction.

[0013] Furthermore, it also includes a connecting rod and a handrail, wherein a handrail is fixedly connected to the upper side of each oblique rod frame, and the middle section of the handrail is fixedly connected to the oblique rod frame through two connecting rods. The handrail is used for workers to hold their hands when climbing to improve the safety of the escalator, and the connecting rod is used to improve the stability of the handrail installation.

[0014] Furthermore, it also includes a movable clamping rod and a clamping block. The movable clamping rod is rotatably connected to one side of the vertical bracket close to the handrail. The clamping block is an L-shaped structure and is fixedly connected to the vertical bracket on the other side. The movable clamping rod is horizontally arranged and the other end is clamped inside the clamping block. The clamping block is used to clamp the end of the movable clamping rod. When the worker climbs onto the standing board, by lowering the movable clamping rod, a protective effect similar to that of the side guard bar can be achieved, further improving the safety of the worker when working on the escalator.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the movable escalator for industrial logistics transportation has the following advantages:

[0016] 1. It has an automatic lifting unit. When workers are working at a high place on the escalator, they can easily control the automatic lifting of the standing board through the control switch installed on the side guardrail to adjust to the appropriate working height. The side guardrail is used to prevent the worker from falling from the side, and can also be used for the worker's hand support. The linkage slide bar can be raised and lowered with the standing board, so that the side guardrail can always protect the workers.

[0017] 2. It has a reliable auxiliary stabilizing unit. When the expansion rod is fully opened outward, the leather foot moves downward a certain distance with the expansion rod and sticks to the bottom surface. By expanding the expansion rod outward, the width of the ground contact surface of the escalator frame can be increased, and a cross-shaped stable structure is formed with the bottom plate, making the escalator more stable as a whole and effectively preventing the escalator from tipping over sideways.

[0018] 3. The utility model has an automatic lifting unit. When workers are working at a high place on the escalator, the control switch installed on the side guard bar can conveniently control the automatic lifting of the standing board to adjust to a suitable working height.

The workers climb onto the standing board 42 through the step plate 9 and stand on the standing board 42 to carry and stack industrial items. The side guard bars 45 are used to provide anti-fall protection from the side of the workers and can also be used for the workers' hands to hold. When the workers are working, the control switch 46 installed on the side guard bars 45 can conveniently control the automatic lifting of the standing board 42 to adjust to a suitable working height. The hydraulic cylinder 43 is used to provide the power required for the lifting of the standing board 42, and the linkage slide bar 44 can be lifted and lowered with the standing board 42, so that the side guard bars 45 can always protect the workers.
