Abstract
Description
Technical Field
[0001] This utility model relates to a cage assembly, and more particularly to a standard section cable guide frame. Background Technology
[0002] A construction hoist, also known as a construction lift, consists of several parts, including a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical system. It is a commonly used construction machine for carrying people and goods. Its unique box-like structure makes it both comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites. Since the hoist moves up and down on the standard sections and its position is not fixed, it needs to be connected to the ground via cables to supply power to the electrical system in the hoist.
[0003] When supplying power through cables, a pulley is used in conjunction with the cable to lower the cable to the ground. Sometimes the standard section is quite high and the cage moves quite high, resulting in a long length of cable suspended in the air. In windy weather, this is actually very unsafe, as the wind will swing the cable wildly, causing damage or even breakage to the cable's outer sheath, which is quite unsafe.
[0004] Therefore, this invention aims to provide a standard cable guide frame that can not only effectively restrict the cable layout, so that the cable is confined to a narrow space even under the influence of strong external wind, but also adjust the area of the restricted area and automatically give way when the trolley passes, without obstructing the trolley's movement. Utility Model Content
[0005] This invention provides a standard cable guide frame that can effectively solve the above-mentioned problems.
[0006] This utility model is implemented as follows:
[0007] A standard cable guide frame includes:
[0008] A cable limiting frame includes an external extension rod locked onto a standard section. A first limiting frame and a second limiting frame are fixed to both ends of the external extension rod. Both the first limiting frame and the second limiting frame are provided with a clearance structure. After the external extension rod is installed, the clearance structure at the corresponding position is opened according to the position of the trolley to make way for the trolley.
[0009] An adjustable limiting component is disposed below the first limiting frame or the second limiting frame. Infrared sensors are provided at both the upper and lower ends of the first limiting frame and the second limiting frame. The adjustable limiting component is in a horizontal state. After the infrared sensor detects that a foreign object is approaching, it flips downward to a vertical state, and after the signal of the infrared sensor disappears, it flips upward to a horizontal state.
[0010] As a further improvement, the first limiting frame and the second limiting frame have the same structural size. The first limiting frame includes two L-shaped rods fixed to the outer extension rod. A fixing plate is provided on one side of the two L-shaped rods facing each other. The clearance structure is movably mounted on the fixing plate.
[0011] As a further improvement, the bottom of the fixing plate is provided with a hole, and the clearance structure includes a movable pin that passes through the bottom hole of the fixing plate. The movable pin is connected to a rotating plate, and the rotating plate is movably attached to the upper end of the fixing plate.
[0012] As a further improvement, the adjustable limiting assembly includes a rotating component disposed below the first limiting frame or the second limiting frame, and a limiting plate is provided on the output end of the rotating component. After the limiting plate is flipped by the rotating component, the cable is limited within the limiting plate.
[0013] As a further improvement, the limiting plate includes an extension shaft sleeved on the output end of the rotating component. The extension shaft is integrally formed with a plate surface, and the inner side of the plate surface is provided with several receiving grooves.
[0014] As a further improvement, the fixed end of the rotating component is provided with a sealing sleeve, which is movably fitted with the extension shaft.
[0015] As a further improvement, a protective steel strip is provided at the position of the rotating component not covered by the L-shaped rod, and the protective steel strip is fixed to the L-shaped rod.
[0016] The beneficial effects of this utility model are:
[0017] As the trolley slides and drives the cable up and down, the cable will sway slightly with the change of the trolley's position and the effect of the wind. However, if the wind suddenly picks up, the position of the cable is difficult to control, and the violently swaying cable is prone to damage, causing the cage to lose power. Therefore, this utility model can form two limiting frames on the outer extension rod by adding a cable limiting frame. One limiting frame is used to make way for the trolley, and the other limiting frame is used to restrain and limit the cable, so that the cable can be confined to a fixed range.
[0018] Although the cable is confined within the cable restraint frame, the size of the cable restraint frame itself cannot be set too small because it needs to be set to allow the trolley to pass through. This results in a relatively large fluctuation range of the cable. Therefore, this invention adds an adjustable limiting component to the cable restraint frame. When the wind suddenly picks up, the position of the adjustable limiting component can be switched, allowing the entire adjustable limiting component to be adjusted from a vertical to a horizontal state. This makes the cable less prone to excessive swinging in a confined space, and it can be switched back to the normal vertical state after the weather returns to normal, without affecting the normal fluctuation of the cable.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] Reference Figures 1-3 As shown, a standard section cable guide frame includes a cable limiting frame 10, comprising an external extension rod 11 locked onto the standard section. A first limiting frame 12 and a second limiting frame 13 are fixed to both ends of the external extension rod 11. Both the first limiting frame 12 and the second limiting frame 13 are provided with clearance structures 14. After the external extension rod 11 is installed, the clearance structure 14 at the corresponding position is opened according to the position of the trolley to allow the trolley to move. An adjustable limiting component 20 is disposed below the first limiting frame 12 or the second limiting frame 13. Infrared sensors are provided at both the upper and lower ends of the first limiting frame 12 and the second limiting frame 13. The adjustable limiting component 20 is in a horizontal state. When the infrared sensor detects an approaching foreign object, it flips downwards to a vertical state, and when the signal from the infrared sensor disappears, it flips upwards to a horizontal state.
[0026] The trolley is installed on the side of the entire cage, and the outer extension rod 11 is also installed on the side of the standard section. Thus, during the operation of the cage, the trolley can restrict the frame 10 through the cable. The trolley setting is prior art and will not be described in detail in this case.
[0027] When the trolley slides, it will pass through the first limit frame 12 or the second limit frame 13. Correspondingly, after the cable passes around the trolley, it will be restricted by the first limit frame 12 or the second limit frame 13, so that the trolley passes through the first limit frame 12 and the cable passes through the second limit frame 13, and vice versa.
[0028] Since the installation position of the trolley is different in different environments, the corresponding direction will also be different when it is matched with the cable limiting frame 10. Therefore, it is necessary to select which side of the clearance structure 14 to use according to the setting direction of the trolley.
[0029] During the process of the trolley sliding and driving the cable up and down, the cable will swing slightly with the change of the trolley's position and the effect of the wind. However, if the wind suddenly picks up, the position of the cable will be difficult to control, and the violently swinging cable is prone to damage, causing the cage to lose power. Therefore, in this embodiment, by adding a cable limiting frame 10, two limiting frames can be formed on the outer extension rod 11. One limiting frame is used to make way for the trolley, and the other limiting frame is used to restrain and limit the cable, so that the cable can be confined to a fixed range.
[0030] The entire limiting frame consists of two sections. Specifically, the first limiting frame 12 and the second limiting frame 13 have the same structural size. The first limiting frame 12 includes two L-shaped rods 121 fixed to the outer extension rod 11. A fixing plate 122 is provided on the opposite side of the two L-shaped rods 121. The clearance structure 14 is movably installed on the fixing plate 122. In fact, the first limiting frame 12 and the second limiting frame 13 can also be other shapes, as long as the trolley can pass through.
[0031] The clearance structure 14 needs to be installed at the end through which the trolley passes, but does not need to be removed at the end through which the trolley does not pass. Therefore, the clearance structure 14 needs to be a movable structure. In this embodiment, the bottom of the fixed plate 122 is provided with a hole. The clearance structure 14 includes a movable pin 141 that passes through the hole at the bottom of the fixed plate 122. The movable pin 141 is connected to a rotating plate 142. The rotating plate 142 is movably attached to the upper end of the fixed plate 122, so that the state of the rotating plate 142 can be adjusted by the movable pin 141 when a change in state is required.
[0032] Although the cable is confined within the cable limiting frame 10, the size of the cable limiting frame 10 itself cannot be set too small because it needs to be set to allow the trolley to pass through. This results in a relatively large fluctuation range of the cable. Therefore, this invention adds an adjustable limiting component 20 to the cable limiting frame 10. When the wind suddenly picks up, the position of the adjustable limiting component 20 can be switched, allowing the entire adjustable limiting component 20 to be adjusted from a vertical to a horizontal state. This makes the cable less prone to excessive swinging in a confined space, and it can be switched back to a normal vertical state after the weather returns to normal, without affecting the normal fluctuation of the cable.
[0033] The adjustable limiting component 20 needs to be set to two states, namely vertical and horizontal. The specific structure for switching its state is as follows: The adjustable limiting component 20 includes a rotating component 21 disposed below the first limiting frame 12 or the second limiting frame 13. A limiting plate 22 is provided on the output end of the rotating component 21. After the limiting plate 22 is flipped by the rotating component 21, the cable is limited within the limiting plate 22. In this embodiment, the rotating component 21 is a rotating motor, and the adjustable limiting component 20 is not provided at the end through which the trolley passes.
[0034] The cable is mainly housed in the limiting plate 22. In this embodiment, the limiting plate 22 includes an extension shaft 221 sleeved on the output end of the rotating member 21. The extension shaft 221 is integrally formed with a plate surface 222. The inner side of the plate surface 222 is provided with several receiving grooves 223. After the adjustable limiting component 20 is flipped to a horizontal position, the cable is housed in the receiving groove 223 or in the gap between the plate surface 222 and the outer extension rod 11.
[0035] To protect the connection between the cable and the rotating part 21, a closed sleeve 224 is provided at the fixed end of the rotating part 21. The closed sleeve 224 is movably fitted with the extension shaft 221. The closed sleeve 224 and the extension shaft 221 are separately provided and movably fitted, so that the use of the closed sleeve 224 is not affected when the extension shaft 221 rotates.
[0036] To prevent falling objects from affecting the rotating component 21, a protective steel strip 211 is provided on the part of the rotating component 21 that is not covered by the L-shaped rod 121. The protective steel strip 211 is fixed to the L-shaped rod 121, thereby providing more comprehensive protection for the top surface of the rotating component 21.
[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
