Description
Technical Field
The invention relates to an installation method and a positioning tool for an escalator guide rail system. More particularly, the invention relates to an escalator installation method and a positioning tool used by the escalator installation method.
Background
The step rail, drive system and truss are important parts of an escalator. In the running process of the escalator, the steps run in the truss along the guide rail under the driving of the driving system, and the stability and the safety are ensured and the deviation of the steps is prevented in the running process.
Therefore, the running of the steps puts high demands on the mounting accuracy of the step guide rails. During escalator installation, an important challenge is how to accurately install the step rails and drive system in the truss. The truss itself is a large-sized welded steel structure, which cannot improve sufficient installation accuracy for the step rail and the drive system technically.
In the installation process of the existing escalator, a step guide rail and a driving system are installed on a truss one by adopting a manual method. Such assembly is very time consuming on the one hand and on the other hand it is difficult to accurately install the step rails and the drive system in the truss, resulting in inefficient assembly of the escalator, less accurate installation and higher costs. Therefore, how to solve the above problems is currently an important issue.
Disclosure of Invention
In order to solve the above known problems, the present invention provides an installation method of an escalator guide rail system including a step guide, a drive system, and a truss, the installation method including the steps of:
positioning the step rail and the drive system outside the truss and positioning and mounting the step rail and the drive system on the positioning tool by using a positioning tool to form a rail-drive system mounting assembly, wherein the positioning tool is detachably connected with the step rail and the drive system,
transporting and installing the guide-drive system installation assembly to a predetermined location of the truss, and
removing the positioning tooling from the rail-drive system mounting assembly mounted to the truss.
According to another embodiment of the invention, the positioning tool comprises a positioning side plate and a lifting appliance detachably connected with the positioning side plate,
the step of forming a rail-drive system mounting assembly comprises:
providing a pre-assembly station that detachably secures the positioning side plates and the drive system,
mounting the step guide rail to the positioning side plate so that the step guide rail is positioned on the outer side surface of the positioning side plate,
providing a lifting device connected to the spreader and lowering the spreader such that the spreader detachably connects the positioning side plates and the drive system to form the rail-drive system mounting assembly.
According to another embodiment of the present invention, the step of transporting and installing the guide rail-drive system installation assembly to a predetermined position within the truss includes:
the lifting device lifts the rail-drive system mounting assembly off the pre-assembly table,
the lifting device places the guide-drive system mounting assembly in a predetermined position within the truss, and
the step guide rail, the driving system and the truss are fixed.
According to another embodiment of the invention the rail-drive system mounting assembly is placed in a predetermined position within the truss by positionally supporting the spreader on support posts disposed opposite the truss from fiducials on the spreader.
According to another embodiment of the invention, the step rail, the drive system and the truss are fixed from the outside of the truss.
According to another embodiment of the invention, the step of removing the positioning tool from the rail-drive system mounting assembly comprises:
separating the positioning tool from the step guide rail and the driving system, and
and enabling the positioning tool to leave the truss through the lifting device.
According to another embodiment of the invention, the positioning side plate is a pair of positioning side plates arranged oppositely, wherein the pair of positioning side plates move in a direction approaching each other with respect to the spreader to disengage from the step rail.
By providing the technical scheme, the mounting method of the escalator guide rail system has the following technical effects:
1. the positioning efficiency is high, and the situation of inaccurate positioning can be obviously reduced. The mounting method of the present invention allows for quick and easy positioning of the step guide rails and drive system of the escalator. Compared with manual adjustment, half of the time is saved;
further, during the fixing of the positioning tooling of the preassembled step rail and drive system to the truss, the step rail and drive system are positioned and clamped by the positioning tooling. Thus, the precise positioning can be checked by the installer by visual inspection throughout the fixing process. Removal of the positioning tooling is only commenced after the step rail and drive system are precisely secured to the truss in the predetermined position. This can significantly reduce instances of positioning inaccuracies.
2. The cost is reduced. Since the length and width of the support of the spreader and the support of the pre-assembly table are adjustable to connect positioning side plates of different sizes and shafts of different sizes, the positioning tool can accommodate various variations. If new products are to be covered in the future, only new positioning side plates with separate positioning elements and clamps need to be produced without any changes to the spreader and pre-assembly station. This will significantly reduce costs.
Furthermore, the positioning tooling allows for accurate positioning of the guide rails and drive elements at locations where precision is required, with reduced tolerance requirements, thereby allowing for more economical assembly.
3. The time for assembling the escalator is saved. Since the step rail and the drive system can be pre-assembled first, the time for final assembly can be saved by 3-4 times compared with the conventional assembly method.
The invention also provides a positioning tool which is used for positioning the step guide rail and the driving system of the escalator guide rail system outside the truss of the escalator guide rail system and positioning and mounting the step guide rail and the driving system on the positioning tool to form a guide rail-driving system mounting assembly.
According to another embodiment of the invention, the positioning side plate comprises a positioning element for positioning the step rail.
According to another embodiment of the invention, the spreader includes a datum point for positioning the track-drive system mounting assembly at a predetermined location within a truss of the escalator track system.
According to another embodiment of the invention the spreader comprises slings for lifting and transport of the spreader.
According to another embodiment of the invention, the spreader comprises a support for detachable connection with the positioning side plate and the drive system, the support being configured to be adjustable in length and width to connect different sizes of the positioning side plate and different sizes of the drive system.
According to another embodiment of the invention, the positioning side plate is movable relative to the spreader such that when the positioning tooling is to be removed from the track-drive system mounting assembly mounted to the truss, the positioning side plate moves out of engagement with the step track.
The positioning tool according to the technical scheme can be repeatedly used, and the following technical effects are achieved:
1. the positioning of the step guide rail and the driving system is realized through the positioning tool.
2. And stabilizing the positioning and positioning of the step rail and the drive system until the step rail and the drive system are fixed to the truss. After the step rail and the driving system are positioned and fixed using the positioning tool, the positioning tool is transported by a lifting device such as a crane and put as a whole at a predetermined position within a truss of the escalator. In this process, the positioning tooling stabilizes the step rail and the drive system in their precise positions.
3. The positioning of the pre-positioned guide rail and the drive system as a whole relative to the truss is achieved by means of a reference point of the spreader.
