Description

Technical Field

[0001] This utility model relates to the field of boiler platform ladder technology, and in particular to a boiler platform ladder that is easy to maintain. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The hot water or steam produced in the boiler can directly provide the heat energy required for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. Boilers are mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises. They are generally equipped with ladders for people to use during maintenance.

[0003] Chinese Patent Publication No. CN2195289U discloses a boiler platform ladder that is easy to quickly retract and extend, including a vehicle body, a support plate installed on one side surface of the vehicle body, and a ladder body disposed above the vehicle body. The feature is that it also includes a retractable assembly disposed above the vehicle body.

[0004] The retraction assembly includes two second fixing blocks symmetrically mounted on the surface of the support plate, a stabilizing rod mounted on one side of the second fixing blocks, and a sliding groove symmetrically opened on the surface of the escalator body and matching the stabilizing rod. The escalator body is slidably connected to the surface of the stabilizing rod through the sliding groove. A first fixing block is hinged to the end face of the escalator body. A first hydraulic telescopic rod is mounted on one side of the support plate. One end of the first hydraulic telescopic rod passes through the support plate and is connected to a control block set on the vehicle body. Connecting rods are symmetrically mounted on both sides of the control block. The ends of the two connecting rods away from the control block are respectively connected to the two first fixing blocks.

[0005] In this existing design, although a retractable assembly can be installed, when the boiler equipment platform needs maintenance, the maintenance personnel can activate the first hydraulic telescopic rod to move the control block at one end, which in turn moves the connecting rods on both sides. This, combined with the stabilizing rod and slide groove on the second fixed block, allows for quick retraction and extension of the escalator body. This is convenient to operate, and the escalator can be retracted when the boiler equipment is not being maintained. It is flexible in use and does not occupy much work space, improving the safety of workshop operations. In addition, the support assembly can improve the stability of the escalator body during use. However, after long-term use, the steps are bound to be damaged. Most common escalators have fixed steps. When one step is damaged, the entire escalator needs to be replaced, which is inconvenient for escalator maintenance and greatly increases the cost of use.

[0006] Therefore, a boiler platform ladder that is easy to maintain is designed to solve the above problems. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example

[0028] Please see Figure 1-5 This utility model provides a technical solution: a boiler platform ladder that is easy to maintain, including a base 1, with casters 2 fixedly installed on the bottom surface of the base 1 for easy movement of the base 1, a support platform 3 fixedly installed on the top surface of the base 1, a handrail 4 fixedly installed on the top surface of the base 1, a fixing block 5 fixedly installed on the top of the handrail 4, the side of the fixing block 5 connected to the support platform 3, and the handrail 4 and the support platform 3 fixedly connected by the fixing block 5. An adjustment component 6 is provided inside the handrail 4, including a sleeve rod 601 and a plug rod 602. A short block 603 is fixedly installed at the bottom end of the sleeve rod 601, and a limit block 604 is fixedly installed at the bottom end of the plug rod 602. The sleeve rod 601 and the plug rod 602 are fixedly connected by bolts 612. A plug block 605 passes through the bottom end of the sleeve rod 601, a long rod 606 is fixedly installed on the surface of the plug block 605, and an installation block 607 is fixedly installed on the back of the sleeve rod 601. A limiting rod 608 is fixedly installed on the bottom surface of the mounting block 607. A tension spring 609 is sleeved on the surface of the limiting rod 608. A locking block 610 is slidably connected to the surface of the limiting rod 608. A groove 611 is provided at the bottom end of the insert block 605 and the top end of the locking block 610. The bottom end of the insert block 605 engages with the groove 611 at the top end of the locking block 610. Through the engagement between the grooves 611, the locking block 610 limits the insertion block 605, thereby fixing the sleeve. At the position of rod 601, the insert block 605 and the sleeve rod 601 are slidably connected. Anti-slip particles 613 are fixedly installed on the top surface of both sleeve rod 601 and insert rod 602. The anti-slip particles 613 are evenly distributed on the top surface of sleeve rod 601 and insert rod 602. The anti-slip particles 613 can increase the friction between the user's foot and the top surface of sleeve rod 601 and insert rod 602, avoid the phenomenon of foot slipping, reduce the probability of safety accidents, and improve safety to a certain extent.

[0029] Working principle: During maintenance, manually press down on the locking block 610. The locking block 610 stretches the tension spring 609, and simultaneously slides on the surface of the limiting rod 608. At this time, the locking block 610 moves away from the groove 611 on the surface of the insert block 605, and the insert block 605 is released from its limiting position. Then pull the insert block 605 outward, and the insert block 605 drives the long rod 606 to move. The long rod 606 disengages from the inside of the handrail 4, at which point the sleeve rod 601 is released from its limiting position. Then lift the sleeve rod 601 and the insert rod 602 upward, so that the short block 603 and the limiting block 604 are disengaged from the handrail 4. At this time, both the sleeve rod 601 and the insert rod 602 are released from their limiting positions, and they can be removed from the inside of the handrail 4 for maintenance. After maintenance, insert the short block 603 and the limiting block 604 into the inside of the handrail 4, and pull down the locking block 610. 0. Insert the insert 605 into the sleeve 601. At this time, the insert 605 drives the long rod 606 into the short block 603. Then, release the hand that pulls the locking block 610. The tension spring 609 loses its external force restriction. Due to its own tension, it drives the locking block 610 to slide upward on the surface of the limiting rod 608 until the groove 611 on the surface of the locking block 610 engages with the groove 611 on the surface of the insert 605. At this time, the sleeve 601 and the insert 602 can be limited and fixed. When it is necessary to adjust the position between the insert 602 and the sleeve 601, rotate the bolt 612 to disengage the bolt 612 from the inside of the sleeve 601 and the insert 602. After adjusting the position of the sleeve 601 and the insert 602, rotate the bolt 612 again to fix the sleeve 601 and the insert 602.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
