A telescoping escalator and apparatus

Abstract

This utility model relates to the technical field of external components of complete equipment, and particularly to a telescopic escalator and equipment. The telescopic escalator includes a fixing member and an escalator detachably connected to the fixing member via a snap-fit ​​structure. The snap-fit ​​structure has two snap-fit ​​positions at different heights. When one snap-fit ​​position is engaged, the escalator is flush against the end face of the fixing member; when the other snap-fit ​​position is engaged, the escalator protrudes from the end face of the fixing member at a predetermined height. This utility model solves the problem that existing escalators, with their protruding structures on the outer side of complete equipment, typically require disassembly, separate packaging, and reassembly when the complete equipment needs to be moved or transported. However, this method results in poor coordination between the escalator and the equipment during transportation, difficulty in reducing packaging materials and costs, and long disassembly and assembly times due to repetitive actions.

Description

Technical Field

[0001] This utility model relates to the technical field of external components of complete equipment, and in particular to a telescopic escalator and equipment. Background Technology

[0002] Existing complete sets of equipment are usually quite tall. When it comes to feeding or maintenance, workers need to climb to the top of the equipment to perform the work. Usually, ladders are installed on the side of the equipment to facilitate the workers' climbing.

[0003] The existing escalators are modular structures, assembled with the main equipment at both ends using bolts. When assembled, the escalator is a raised structure on the outer side of the main equipment (e.g., Figure 4 As shown in the figure, when the whole equipment needs to be moved or transported, it is usually disassembled and packaged separately, and then reassembled when the whole equipment is moved or installed. However, this method results in poor coordination between the escalator and the equipment during transportation, and it is difficult to reduce the packaging materials and packaging costs during transportation. In addition, the disassembly and assembly process is repetitive, resulting in a long disassembly and assembly time.

[0004] Therefore, this utility model proposes a telescopic escalator and equipment. Utility Model Content

[0005] The utility model of this invention provides a telescopic escalator and equipment, which mainly solves the problems of existing escalators being protruding structures set on the outer side of the whole equipment. When the whole equipment needs to be moved or transported, the escalator usually needs to be disassembled, packaged and transported separately, and then reassembled. However, this method results in poor coordination between the escalator and the equipment during transportation, and it is difficult to reduce the packaging materials and packaging costs during transportation. In addition, the disassembly and assembly process involves repetitive actions, resulting in a long disassembly and assembly time.

[0006] This utility model proposes a telescopic escalator, comprising:

[0007] Fasteners;

[0008] The escalator is detachably connected to the fixing member via a snap-fit ​​structure, and the snap-fit ​​structure has two snap-fit ​​positions with different heights; when one of the snap-fit ​​positions is set, the escalator is set close to the end face of the fixing member, and when the other snap-fit ​​position is set, the escalator protrudes from the end face of the fixing member at a preset height.

[0009] Preferably, the engaging structure includes:

[0010] A tubular component is disposed on the end face of the fixing member away from the escalator, and the depth direction of the tubular component is perpendicular to the end face of the fixing member and away from the escalator.

[0011] A rod-shaped member, protruding from the end face of the escalator facing the fixing member;

[0012] The rod-shaped member is connected to the tubular member through a sleeve, and the rod-shaped member can slide along the length of the tubular member to achieve two different locking positions.

[0013] Preferably, the engaging structure further includes:

[0014] Locking pin;

[0015] The rod-shaped member has two limiting holes spaced apart along the axial direction.

[0016] A pin hole is formed on the tubular component;

[0017] The limiting hole on the rod-shaped member is coaxially aligned with the pin hole of the tubular member, and the locking pin is inserted into the coaxially aligned limiting hole and the pin hole to lock the rod-shaped member and the tubular member.

[0018] Preferably, the number of the engaging structures is several, and they are spaced apart along the height direction of the escalator and the fixing member.

[0019] Preferably, the height of the fastener is less than the height of the escalator, and the fastener fully covers all the steps of the escalator.

[0020] Preferably, the escalator further includes:

[0021] The handrail is located at the upper end of the escalator and is elliptical in shape.

[0022] This embodiment also proposes a device including the aforementioned telescopic escalator, wherein the fixing member of the telescopic escalator is disposed on the outer side of the device, and the length direction of the telescopic escalator is arranged in the same direction as the height direction of the device;

[0023] In the transport state, the escalator and the fixing components are tightly attached to the outer side of the equipment;

[0024] In use, the escalator protrusion is located on the outer side of the device.

[0025] Preferably, the end of the tubular member on the fixing member of the telescopic escalator away from the fixing member is fixed to the outer side of the device.

[0026] Preferably, the equipment is a rotary drilling rig.

[0027] As can be seen from the above, the following beneficial effects can be obtained by applying the technical solution provided by this utility model:

[0028] First, the telescopic escalator proposed in this utility model can be quickly extended and retracted, and is set to abut the outer side of the whole machine. During transportation, the escalator and the whole machine can be folded up for transportation, reducing packaging costs and ensuring the synergy between the escalator and the whole machine. When in use, the escalator can be pulled out directly, eliminating the time and procedures for disassembling and assembling the escalator.

[0029] Secondly, the telescopic escalator proposed in this utility model has a locking structure with two locking positions, which realizes the telescopic setting of the escalator on the whole machine, adapting to the transportation and use states respectively, and ensuring that the escalator is fixed in any state, ensuring the structural integrity of the escalator during transportation and the structural stability of the escalator during use.

[0030] Third, the telescopic escalator proposed in this utility model uses locking pins to fix the tubular and rod-shaped parts in different engagement positions, further ensuring the fixation degree and stability of the tubular and rod-shaped parts;

[0031] Fourth, the telescopic escalator proposed in this utility model is equipped with a number of interlocking structures that are spaced apart, which ensures the overall static state of the escalator during transportation and the stability of the escalator when workers climb it during use.

[0032] Fifth, the tubular component on the telescopic escalator proposed in this utility model is fixed to the equipment and can be used as the support leg of the telescopic escalator, thus simplifying the structure of the telescopic escalator. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0039] Existing escalators have a raised structure on the outer side of the whole machine. When the whole machine needs to be moved or transported, the escalator usually needs to be disassembled, packaged and transported separately, and then reassembled. However, this method results in poor coordination between the escalator and the equipment during transportation, and it is difficult to reduce the packaging materials and packaging costs during transportation. In addition, the disassembly and assembly process involves repetitive actions, resulting in a long disassembly and assembly time.

[0040] like Figures 1-3 As shown, in order to solve the above problems, this embodiment proposes a telescopic escalator, including a fixing member 10 and an escalator 20 detachably connected to the fixing member 10 through a snap-fit ​​structure, and the snap-fit ​​structure has two snap-fit ​​positions with different heights; when one snap-fit ​​position is set, the escalator 20 is set close to the end face of the fixing member 10, and when the other snap-fit ​​position is set, the escalator 20 is set at a preset height protruding from the end face of the fixing member 10.

[0041] Preferably, in this embodiment, the fixing member 10 is disposed on the outer side of the whole machine. Therefore, during transportation, the escalator 20 and the fixing member 10 are closely disposed on the outer side of the whole machine; in use, the escalator 20 protrudes from the outer side of the whole machine.

[0042] Preferably, in this embodiment, the fastener 10 is made of metal, which can ensure the strength and rigidity of the fastener 10, thereby ensuring that the detachable escalator 20 and the whole equipment are fixed in their installation positions.

[0043] Preferably, in this embodiment, the fixing member 10 completely covers all the steps on the escalator 20. Preferably, but not limited to, in this embodiment, the height of the fixing member 10 is equal to the height of the steps on the escalator 20, that is, the height of the fixing member 10 is less than the overall height of the escalator 20. Since each step is subjected to a strong force when the user climbs, having the fixing member 10 cover the steps further enhances the tightness of the connection between the escalator 20 and the fixing member 10, thereby ensuring the stability of the escalator 20.

[0044] In this embodiment, the distance between the escalator 20 and the fixing member 10 can be adjusted by setting the fixing member 10. Due to the setting relationship between the fixing member 10 and the whole machine, the extension and retraction setting of the escalator 20 on the whole machine can be further realized. During transportation, the width extension distance of the escalator 20 on the surface of the whole machine is reduced, which can realize the coordinated transportation of the whole machine and the escalator 20, while avoiding repeated disassembly and assembly of the escalator 20.

[0045] More specifically, in this embodiment, the engaging structure includes a tubular member 11 and a rod-shaped member 21; the tubular member 11 is disposed on the end face of the fixing member 10 away from the escalator 20, and the depth direction of the tubular member 11 is perpendicular to the end face of the fixing member 10 and away from the escalator 20; the rod-shaped member 21 protrudes from the end face of the escalator 20 facing the fixing member 10; the rod-shaped member 21 is inserted and connected to the tubular member 11, and the rod-shaped member 21 can slide along the length direction of the tubular member 22 to achieve two different engaging positions.

[0046] Preferably, the engaging structure further includes a locking pin 30; the rod-shaped member 21 has two limiting holes spaced apart along the axial direction; the tubular member 11 has a pin hole formed therein, and any limiting hole on the rod-shaped member 21 is coaxially aligned with the pin hole of the tubular member 11. The locking pin 30 is inserted into the coaxially aligned limiting hole and pin hole to lock the rod-shaped member 21 and the tubular member 11.

[0047] In a preferred embodiment of this example, any engaging structure includes two parallel tubular members 11 and two parallel rod-shaped members 21, as well as two identical locking pins 30. Without limitation, in this embodiment, the two tubular members 11 are evenly distributed at any horizontal height on the fixing member 10 away from the end face of the escalator 20, and the two rod-shaped members 21 are evenly distributed at any horizontal height on the end face of the escalator 20 facing the fixing member 10. The two rod-shaped members 21 and the two tubular members 11 move synchronously, achieving coaxial alignment of the two limiting holes and the two pin holes, and are fixed by the two locking pins 30.

[0048] In another preferred embodiment of this example, there are multiple engaging structures that are spaced apart along the height direction of the telescopic escalator, wherein all tubular members 11 on all engaging structures are located on the same vertical line, all rod-shaped members 21 are located on the same vertical line, and the vertical line is parallel to the height of the telescopic escalator.

[0049] In this embodiment, during transportation, the escalator 20 is pushed to the bottom. The rod-shaped member 21 of the escalator 20 has two limiting holes. The limiting hole on the escalator 20 near the handrail 22 is aligned with the pin hole on the tubular member 11 of the fixing member 10, and the locking pin 30 is inserted for fixation. This ensures that the width does not exceed the limit during transportation. When using the escalator 20, the locking pin is pulled out, and the escalator 20 is pulled out until the limiting hole on the rod-shaped member 21 at the far end of the escalator 20 is aligned with the pin hole on the tubular member 11 of the fixing member 10, and the locking pin 30 is inserted for fixation.

[0050] More specifically, the fastener 10 is arranged in a plate-like structure, and the plane of the fastener 10 is parallel to the plane of the escalator 20.

[0051] Preferably, the fastener 10, which is arranged in a plate-like structure, can minimize its width occupied on the whole machine, thereby reducing the width occupied by the telescopic escalator 20 when it is retracted, and at the same time, the plate-like structure ensures the structural stability of the escalator 20 when a user is climbing vertically.

[0052] More specifically, the escalator 20 is also equipped with a handrail 22, which is located at the upper end of the escalator 20; the handrail 22 is elliptical in shape.

[0053] Preferably, in this embodiment, the handrail 22 is suspended at the top of the fixing member 10 and is independently set from the fixing member 10.

[0054] Preferably, in this embodiment, the handrail 22 of the escalator 20 is provided for users to grasp while climbing, ensuring the safety of the climbing process. The elliptical shape can minimize the injury to the user's hands from sharp edges.

[0055] Example 2

[0056] To address the aforementioned problems, this embodiment also proposes a device including the telescopic escalator described in Embodiment 1. The telescopic escalator is disposed on the outer side of the device, and the length direction of the escalator 20 is aligned with the height direction of the device. In the transport state, the escalator 20 and the fixing member 10 are tightly attached to the outer side of the device; in the use state, the escalator 20 protrudes from the outer side of the device.

[0057] Preferably, in this embodiment, the end of the tubular member 11 on the fixing member 10 of the telescopic escalator away from the fixing member 10 is fixed to the outer side of the equipment. In this embodiment, the tubular member 11 on the fixing member 10 of the telescopic escalator can be used as a support member of the telescopic escalator.

[0058] Preferably, in this embodiment, the equipment is a rotary drilling rig.

[0059] In summary, this embodiment proposes a telescopic escalator and device. By using a fixing member set on the outer side of the whole machine, the escalator can be retracted on the fixing member to achieve a narrower transport state, and the escalator can be raised on the fixing member to provide a foothold for the user.

[0060] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
