Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0030] As described in the background technology, the design of traditional counterweight frames often focuses on the stability and load-bearing capacity of the structure, but ignores the convenience of maintenance and the optimization of space utilization. In the daily maintenance of elevators, the replacement of counterweight blocks is a common and important task.

The take-in and take-out opening 102 is used for connecting and separating the counterweight body 2 and the straight beams 1.
[0034] The counterweight frame for a steel belt elevator provided by the utility model has a take-in and put-out port 102, and the design of the take-in and put-out port 102 greatly facilitates the process of taking out and replacing the counterweight block body 2, thereby facilitating maintenance, improving the convenience and efficiency of elevator maintenance, and reducing maintenance costs and time.
[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0038] Example 1, please refer to Figure 1-Figure 3 A counterweight frame for a steel belt elevator comprises two straight beams 1, a plurality of counterweight bodies 2 are arranged between the two straight beams 1, and a pick-up and release port 102 is opened on one side of the two straight beams 1, and the pick-up and release port 102 is used for connecting and separating the counterweight body 2 from the straight beams 1. The present application sets up the pick-up and release port 102, and the design of the pick-up and release port 102 greatly facilitates the removal and replacement process of the counterweight body 2, thereby facilitating maintenance, improving the convenience and efficiency of elevator maintenance, and reducing maintenance costs and time.
[0039] Further, such as Figure 1-Figure 3 As shown, a limiting groove 101 is provided on the side where the two straight beams 1 are close to each other, and a limiting block 201 is provided at both ends of the counterweight body 2. The limiting block 201 is plugged into the inner wall of the limiting groove 101. After the limiting block 201 is plugged into the limiting groove 101, the counterweight body 2 can be limited.
[0040] Further, such as Figure 2As shown, the access opening 102 is connected to the limit groove 101, and a baffle 103 is installed on the side of the straight beam 1 by bolts. The baffle 103 is used to block the access opening 102 to prevent the counterweight body 2 from escaping from the access opening 102 during use. The baffle 103 can be removed by unscrewing the bolts connecting the baffle 103 to release the access opening 102.
[0041] Further, such as Figure 1 As shown, an upper beam plate 4 is installed between the tops of the two straight beams 1 , and a steel belt body 6 is arranged on the upper beam plate 4 .
[0042] Further, such as Figure 1 As shown, a lower beam plate 5 is installed between the bottoms of the two straight beams 1 , and a buffer seat 501 is installed at the bottom of the lower beam plate 5 . The buffer seat 501 is used for buffering the lower beam plate 5 .
[0043] Embodiment 2 further optimizes the counterweight frame for the steel belt elevator provided in Embodiment 1. Specifically, Figure 1 As shown, a limit plate 3 is installed on the inner wall of the limit groove 101 by bolts, and the limit plate 3 is in contact with the uppermost limit block 201. The limit plate 3 limits the uppermost limit block 201, so that the counterweight body 2 can be limited, thereby improving the stability of several counterweight bodies 2 located between the two straight beams 1. The limit plate 3 can be removed after unscrewing the screws connecting the limit plate 3, and then the baffle 103 is removed and the counterweight body 2 is pushed upward. When the limit block 201 corresponds to the access port 102, the counterweight body 2 can be pulled horizontally to remove the limit block 201 from the access port 102.
[0044] Embodiment 3 further optimizes the counterweight frame for the steel belt elevator provided in Embodiment 1. Specifically, Figure 5-Figure 7 As shown, two pressing plates 702 are placed on the top of the counterweight body 2 at the top, a limit strip 7 is fixedly connected between the two pressing plates 702 , and side plates 701 are fixedly connected on both sides of the limit strip 7 .
[0045] Furthermore, a limiting member is provided between the two side plates 701 and the upper beam plate 4 . After the limiting member limits the limiting strip 7 , the limiting strip 7 can limit the limiting block 201 and the counterweight body 2 through the pressing plate 702 .
[0046] Further, such as Figure 6 and Figure 7As shown, the limiting member includes two limiting rods 703, and the two limiting rods 703 are both inserted between the two side plates 701. The tops of the two limiting rods 703 are each provided with a groove 704, and the two grooves 704 are each fixedly connected with a connecting shaft 705, and the outer surfaces of the two connecting shafts 705 are each sleeved with a connecting seat 706, and the tops of the two connecting seats 706 are each fixedly connected with a mounting seat 707, and the mounting seat 707 is fixedly connected to the upper beam plate 4. The limiting bar 7 can be limited by the mounting seat 707 and the limiting rod 703 pressing against the limiting bar 7, and the outer surface of the connecting seat 706 is in contact with the inside of the groove 704. The limiting rod 703 can be limited by the friction force between the groove 704 and the connecting seat 706, so that the limiting rod 703 will not fall down by itself after rotating to a horizontal state.
[0047] Further, such as Figure 6 and Figure 7 As shown, the outer surfaces of the two limit rods 703 are sleeved with limit rings 708, and the sides of the two side panels 701 that are close to each other are each provided with a side groove 709, the inner wall of the side groove 709 is plugged into the limit ring 708, and a magnet can be embedded on the inner wall of the limit ring 708. The magnet can limit the position of the limit ring 708, so that the limit ring 708 can be sucked onto the limit rod 703 or the mounting seat 707, and the limit rod 703 can be limited by the limit ring 708 being sleeved on the outer surface of the limit rod 703.
[0048] Pull the limit ring 708 upward so that the limit ring 708 is sleeved on the outer surface of the mounting seat 707, then rotate the limit rod 703 to a horizontal position with the connecting shaft 705 as the center, pull the limit strip 7 upward, and when the pressure plate 702 is aligned with the access port 102, take the pressure plate 702 out of the access port 102, then pull the counterweight body 2 upward, and when the limit block 201 is at the access port 102, take the counterweight body 2 out of the access port 102. During installation, insert the limit block 201 into the limit groove 101 from the access port 102, and finally insert the pressure plate 702 into the limit groove 101 from the access port 102, rotate the limit rod 703 downward so that the limit rod 703 is against the limit strip 7, and then push the limit ring 708 downward so that the limit ring 708 is plugged into the side groove 709.
