[0024] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.
[0025] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.
[0026] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0027] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.
[0028] The present invention provides a machine base 100 for a traction machine, such as Figure 1 and Figure 2 As shown, the base 100 includes a base body 1 .
[0029] Two support members 2 are provided at the bottom of the base body 1. The base body 1 and the support members 2 are an integral structure, and the two support members 2 cooperate to support the base body 1. One side of the support member 2 is recessed toward the other side to form a junction box 3 with an embedded groove structure. By providing two support members 2 integrally formed with the base body 1, the two support members 2 can support the base body 1, and by recessing the two support members 2 to form the junction box 3 in the shape of an embedded groove, the junction box 3 is an embedded structure integrally cast with the base body 1, which can simplify the structure, shorten the assembly time, reduce costs, and make the base 100 small in size and occupy less hoistway space. The junction box 3 is provided on the support member 2 at the bottom of the base body 1, which can facilitate regular maintenance by maintenance operators.
[0030] In some embodiments, the base body 1 has a front and a back facing away from the front, and the side of the support member 2 close to the front is recessed inward toward the back to form the junction box 3 with the embedded groove structure. The front of the base body 1 refers to the side facing the operator when the base 100 is installed in the hoistway, and the back refers to the side facing away from the operator. By forming the junction box 3 with the embedded groove structure on the front of the base body 1, when the maintenance operator stands on the car or in the machine room to perform regular maintenance on the traction machine, he or she can directly face the components that need maintenance in the junction box 3, which can greatly improve the convenience and effectiveness of maintenance, reduce the difficulty of maintenance, and improve efficiency.
[0031] In some embodiments, the groove wall of the junction box 3 includes a first groove wall 31 and a second groove wall 32. The first groove wall 31 extends downward and outward along the height direction of the base body 1, then bends back to form a bent structure. The second groove wall 32 extends downward and outward along the height direction of the base body 1, then bends back to form a bent structure. The bend of the first groove wall 31 is at a different height than the bend of the second groove wall 32. The outward oblique extension of the first and second groove walls 31 and 32 refers to the groove walls being inclined toward a side away from the center of the junction box 3. Specifically, the height direction of the base body 1 refers to the direction perpendicular to the mounting surface of the mounting platform when the base 100 is installed in the hoistway, that is, the Y-axis direction in the three-dimensional plane. Among them, the junction box 3 forms a bent groove wall through its first groove wall 31 and the second groove wall 32, which can make the groove width of the junction box 3 gradually increase downward in the height direction of the base body 1 and then gradually decrease, thereby adapting to the shape structure of the base body 1, and can increase the accommodating space of the junction box 3 in the limited space in the support member 2, and the irregular shape of the junction box 3 structure can also improve the force performance and operation reliability of the base 100.
[0032] In some embodiments, the first groove wall 31 includes a first section 311 and a second section 312 connected to the first section 311. The first section 311 extends downward and outward along the height direction of the base body 1, and the second section 312 is vertically arranged. The second groove wall 32 includes a third section 321 and a fourth section 322 connected to the third section 321. The third section 321 extends downward and outward along the height direction of the base body 1, and the fourth section 322 extends downward and inward along the height direction of the base body 1. The spacing between an end of the first section 311 away from the second section 312 and an end of the third section 321 away from the fourth section 322 is a first spacing, and the spacing between an end of the second section 312 away from the first section 311 and an end of the fourth section 322 away from the third section 321 is a second spacing, and the first spacing is smaller than the second spacing.
[0033] In some embodiments, the second groove wall 32 is disposed on a side close to the base body 1, and the curvature of the second groove wall 32 is greater than the curvature of the first groove wall 31. The curvature of the second groove wall 32 being greater than the curvature of the first groove wall 31 allows the groove shape of the junction box 3 close to the base body 1 to adapt to the shape of the base body 1. Furthermore, the junction box 3 has an irregular structure, which can maximize the space for accommodating the junction box 3 while ensuring the good structural strength of the support member 2.
[0034] In some embodiments, the height of the bend of the first groove wall 31 is higher than the height of the bend of the second groove wall 32. The groove-shaped junction box 3 can further increase the structural strength of the support member 2, thereby making the overall structural strength of the base 100 higher.
[0035] In some embodiments, a wire outlet hole 33 is formed near the bottom of the first slot wall 31. The first slot wall 31 is located on a side away from the base body 1, that is, the wire outlet hole 33 is located on the outside of the base body 1 where the junction box 3 is located. Wires can pass through the wire outlet hole 33 for line connection, facilitating wiring operations.
[0036] In some embodiments, the inner wall of the first groove wall 31 is provided with at least one reinforcing rib 34. The side of the support member 2 closest to the front is recessed toward the back in the direction of the depth of the embedded groove, and the reinforcing rib 34 is provided on the first groove wall 31 along the depth of the embedded groove. The reinforcing rib 34 is provided along the depth of the embedded groove on the first groove wall 31, forming an L-shaped connection with the back of the support member 2. This L-shaped connection fully utilizes the structural reinforcement effect of the reinforcing rib 34, thereby increasing the structural strength of the machine base 100, improving the load-bearing performance and operational reliability of the traction machine, and thus ensuring a smoother elevator ascent and descent. Specifically, the reinforcing rib 34 is provided at the second section 312 of the first groove wall 31.
[0037] In some embodiments, the support member 2 includes a support column 21 and a support plate 22. The base body 1 is supported on the support plate 22 via the support column 21. The junction box 3 is disposed on the support column 21. The support column 21 and the support plate 22 are connected in an inverted T-shape. The inverted T-shaped connection between the support column 21 and the support plate 22 provides stable support for the base 100 and provides sufficient space for the embedded junction box 3.
[0038] In some embodiments, the two junction boxes 3 are centrally symmetrically arranged relative to the central axis of the base body 1 so that the base 100 as a whole is evenly stressed and is easy to install and assemble.
[0039] An embodiment of the present invention further provides a traction machine, which includes a traction machine body and the machine base 100 as described above, wherein the traction machine body is disposed on the machine base 100 .
[0040] The traction machine is provided with a machine base 100, and two integrally formed support members 2 are provided on the machine base body 1 of the machine base 100. The two support members 2 can support the machine base body 1, and the junction box 3 in the shape of an embedded groove is formed by recessing the two support members 2, so that the junction box 3 is an embedded structure cast integrally with the machine base body 1, which can simplify the structure, shorten the assembly time, reduce costs, and make the machine base 100 small in size and occupy a small hoistway space. Combined with the junction box 3 being provided on the support member 2 at the bottom of the machine base body 1, it can be convenient for the maintenance operator to perform regular maintenance on it.
[0041] Based on the above-described traction machine, an embodiment of the present invention further provides an elevator device, comprising an elevator car and the above-described traction machine, wherein the traction machine is connected to the elevator car and enables the elevator to ascend and descend within the elevator shaft. This device also reduces the number of traction machine components, shortens assembly time, and reduces costs. Furthermore, the device can reduce the overall dimensions of the machine base 1, occupying less hoistway space and facilitating regular maintenance.
[0042] The above embodiments are not exhaustive of the present invention, and there may be many other embodiments not listed. Any replacements and improvements made without violating the concept of the present invention are within the scope of protection of the present invention.
