Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a floor parking pedal for a construction elevator. Background Art

[0002] At present, construction elevators are often used in various construction projects. When installing construction elevators, it is necessary to ensure that there is a 100mm-300mm gap between the edge of the cage and the edge of the building; however, when in use, construction elevators often stop at various floors to get people up and down or transport construction materials. According to the safety control requirements of the construction site, relevant measures need to be set up to connect the gap between the edge of the construction elevator cage and the edge of the building. According to the visit investigation, most construction sites use steel pedals of corresponding sizes to be placed in the cage. Every time the elevator stops, the people in the elevator drag them to the top of the gap between the cage and the building to overlap for the passage of people and construction materials; some construction sites have modified and fixed the steel pedals, such as welding the steel pedals to the cage door with bearings and setting handles. When stopping, the people in the elevator also flip the pedals over and overlap them on the building structure for passage. This method avoids the risk of the steel pedals not being fixed, and the rotation of the bearing structure is relatively labor-saving and convenient compared to dragging;

[0003] However, it has been observed that the existing modification method, on the one hand, requires manual flipping and overlapping of the steel pedals every time the elevator switches to a floor, which is time-consuming and laborious. In addition, the steel pedals need to be placed inside the elevator near the opening during the elevator lifting process, occupying a certain amount of elevator internal space, resulting in low utilization of the elevator's internal space. For this reason, the above defects are now improved.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Summary of the Invention

[0005] The purpose of the present invention is to provide a construction elevator floor stop pedal to solve the problem of the elevator pedals in the prior art proposed in the above background technology. Each time the elevator switches floors for construction, the pedals need to be manually overlapped, which is time-consuming and labor-intensive and reduces construction efficiency. In addition, during the lifting process of the elevator, the pedals are placed at the opening of the elevator and occupy a certain amount of internal space of the elevator, resulting in low utilization of the internal space of the elevator.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The construction elevator floor stop pedal includes an elevator body located in an elevator gap in the floor, and also includes:

[0008] The step mounting unit comprises a step body slidably arranged in the bottom of the elevator body and used for mounting on the elevator gap between the elevator body and the floor bottom plate;

[0009] The elevator door opening and closing unit includes a door assembly that slides up and down at the opening of the elevator body to close the elevator opening, and a driving assembly that is located at the upper end of the elevator body to drive the door assembly to open and synchronously drive the pedal body to overlap the elevator seam.

[0019] Furthermore, pulleys are fixedly sleeved on the outer sides of the two groups of the first driven shafts;

[0020] The two groups of pulleys are directly connected by belts, so that the rotation of one driven shaft can drive the other group of driven shafts to rotate synchronously.

[0022] The step erection unit includes:

[0023] The pedal body is slidably inserted into the bottom of the elevator body, and the bottom of the elevator body is provided with a retreat groove for accommodating the pedal body;

[0025] The rack is fixedly connected to the lower end of the groove and is used for cooperating with the driving assembly to drive the pedal body to move.

[0026] Furthermore, the driving assembly further includes:

[0027] a third helical gear, fixedly sleeved on the outer side of the first driven shaft;

[0029] The third driven shaft is rotatably connected to the interior of the elevator body and is located below the second driven shaft. The third driven shaft is perpendicular to the second driven shaft and is used to drive the pedal body to perform overlapping work.

[0030] Furthermore, one end of the third driven shaft close to the fifth helical gear is fixedly connected to a sixth helical gear meshing with the fifth helical gear;

[0031] The third driven shaft is located at one end of the pedal body and is fixedly connected to a second spur gear for adjusting the movement of the pedal body.

[0032] Furthermore, the outer diameter of the second helical gear is greater than the outer diameter of the sixth helical gear, and is used to reduce the speed of rotation of the third driven shaft.

[0033] Furthermore, the pedal body is provided with an inclined slope on one side of the open end of the elevator body, for transferring objects on the floor to the upper end of the pedal body via the inclined slope.

[0034] Furthermore, support beams for protecting the elevator body are provided at the upper end of the floor and at the four corners of the elevator body;

[0035] The opening width of the elevator body is smaller than the distance between two adjacent groups of support beams.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] The present invention drives the elevator door assembly to move upward along the elevator body through the driving assembly, so that the elevator door assembly is opened. At the same time, the driving assembly also synchronously drives the pedal body to move outward along the elevator body, so that one end of the pedal body moves from the bottom of the elevator body to above the elevator gap and overlaps the floor, completing the automatic overlapping of the pedal body with high overlapping efficiency. By arranging the pedal body inside the bottom of the elevator body, it is ensured that the pedal body does not occupy the internal space of the elevator body, thereby improving the utilization rate of the internal space of the elevator.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] See also Figure 1-9 , the present invention provides a technical solution:

[0050] The construction elevator floor stop pedal includes an elevator body 102 arranged in an elevator gap 1001 of a floor 100, and further includes:

[0051] The step mounting unit 2 includes a step body 21 slidably mounted in the bottom of the elevator body 102 and configured to be mounted on the elevator gap 1001 between the elevator body 102 and the floor bottom plate;

[0052] The elevator door opening and closing unit 1 includes a ladder door assembly 12 that slides up and down at the opening of the elevator body 102 for closing the elevator opening, and a driving assembly 11 that is arranged at the upper end of the elevator body 102 for driving the ladder door assembly 12 to open and synchronously drive the pedal body 21 to overlap the elevator seam 1001.

[0053] It should be noted that: when the elevator body 102 rises to the floor 100 of the corresponding height and is ready to open the elevator door, the drive assembly 11 is started, and the drive assembly 11 drives the elevator door assembly 12 to move upward along the elevator body 102, so that the elevator door assembly 12 is opened. At the same time, the drive assembly 11 also synchronously drives the pedal body 21 to move outward along the elevator body 102, so that one end of the pedal body 21 moves from the bottom of the elevator body 102 to the top of the elevator seam 1001 and overlaps with the floor 100, completing the automatic overlapping of the pedal body 21, with high overlapping efficiency. By arranging the pedal body 21 inside the bottom of the elevator body 102, it is ensured that the pedal body 21 does not occupy the internal space of the elevator body 102, thereby improving the utilization rate of the internal space of the elevator.

[0054] As an improvement, Figure 2-4 As shown, the elevator door assembly 12 includes:

[0055] The elevator door 121 is inserted into the elevator body 102 for sliding up and down. The elevator body 102 is provided with a guide groove 1022 for guiding the elevator door 121.

[0056] The tooth grooves 122 are provided on both sides of the elevator door 121 . The tooth grooves 122 are provided with teeth that cooperate with the drive assembly 11 to adjust the opening and closing of the elevator door 121 .

[0057] Furthermore, the driving assembly 11 includes:

[0058] The first spur gear 111 is provided with two sets, each meshing with the teeth in the corresponding tooth groove 122;

[0059] A first driven shaft 112 is fixedly inserted into the first spur gear 111;

[0060] A first helical gear 113 is fixedly connected to one end of the first driven shaft 112;

[0061] A drive motor 114 is mounted on the upper end of the elevator body 102 . A second helical gear 115 is mounted on the driving end of the drive motor 114 and is engaged with one of the first helical gears 113 , so as to drive the first helical gear 113 to rotate.

[0062] The brackets 116 are provided in two groups and are installed at the upper end of the elevator body 102 and located outside the first driven shaft 112 , so as to support the first driven shaft 112 . The first driven shaft 112 is rotatably connected to the brackets 116 .

[0063] Furthermore, Figure 4 As shown, the outer sides of the two sets of the first driven shafts 112 are fixedly sleeved with pulleys 1121;

[0064] The two groups of pulleys 1121 are directly connected via a belt 1122 so that the rotation of one driven shaft can drive the other group of driven shafts to rotate synchronously.

[0065] Among them, Figure 5 , Figure 8-9 As shown, the pedal setting unit 2 includes:

[0066] The pedal setting unit 2 includes:

[0067] The pedal body 21 is slidably inserted into the bottom of the elevator body 102. The bottom of the elevator body 102 is provided with a retreat groove 1021 for accommodating the pedal body 21.

[0068] There are two groups of grooves 22, which are respectively opened on both sides of the pedal body 21;

[0069] The rack 23 is fixedly connected to the lower end of the groove 22 and is used to cooperate with the driving assembly 11 to drive the pedal body 21 to move.

[0070] As an improvement, Figure 2-4 As shown, the driving assembly 11 further includes:

[0071] A third helical gear 117 is fixedly sleeved on the outer side of the first driven shaft 112;

[0072] The second driven shaft 118 is provided with two sets and is rotatably connected to the interior of the elevator body 102. The upper end of the second driven shaft 118 is fixedly connected to a fourth helical gear 1181 meshing with the third helical gear 117. The lower end of the second driven shaft 118 is fixedly connected to a fifth helical gear 1182.

[0073] The third driven shaft 119 is rotatably connected to the interior of the elevator body 102 and is located below the second driven shaft 118. The third driven shaft 119 is perpendicular to the second driven shaft 118 and is used to drive the pedal body 21 to perform overlapping work.

[0074] Furthermore, one end of the third driven shaft 119 close to the fifth bevel gear 1182 is fixedly connected to a sixth bevel gear 1191 meshing with the fifth bevel gear 1182 ;

[0075] One end of the third driven shaft 119 located at the pedal body 21 is fixedly connected to a second spur gear 1192 for adjusting the movement of the pedal body 21 . The second spur gear 1192 is meshed with the rack 23 .

[0076] Furthermore, Figure 5 As shown, the outer diameter of the second helical gear 115 is greater than the outer diameter of the sixth helical gear 1191 , and is used to reduce the speed of the rotation of the third driven shaft 119 .

[0077] The pedal body 21 is provided with an inclined slope 211 on one side of the open end of the elevator body 102 , for transferring objects on the floor 100 to the upper end of the pedal body 21 via the inclined slope 211 .

[0078] In addition, support beams 101 for protecting the elevator body 102 are provided at the upper end of the floor 100 and at the four corners of the elevator body 102;

[0079] The opening width of the elevator body 102 is smaller than the distance between two adjacent groups of support beams 101 .

[0080] It should be added that, Figure 8 As shown, when the elevator body 102 of the present invention is lifted to the corresponding floor and stops, the plane where the lower end of the pedal body 21 is located is not lower than the plane where the upper end of the corresponding floor 100 is located, ensuring that the pedal body 21 does not hit one side of the floor 100 during the process of moving out of the retreat groove 1021.

[0081] It should be noted that: in the specific implementation process of the present invention, Figure 3-9As shown, when the elevator body 102 rises to the corresponding floor and stops, the drive motor 114 is started, and the drive motor 114 drives the first bevel gear 113 to rotate through the second bevel gear 115. The first bevel gear 113 drives the first spur gear 111 to rotate through the first driven shaft 112. The first spur gear 111 drives the elevator door 121 to move upward along the guide groove 1022 by meshing with the teeth in the tooth groove 122, so that the elevator door 121 is opened. At the same time, the first driven shaft 112 also drives the fourth bevel gear 1181 to rotate through the third bevel gear 117. The fourth bevel gear 1181 drives the fourth bevel gear 1181 through the second driven shaft 112. The shaft 118 drives the fifth bevel gear 1182 to rotate, and the fifth bevel gear 1182 drives the second spur gear 1192 to rotate via the third driven shaft 119. The second spur gear 1192 drives the pedal body 21 to move along the retreat groove 1021 by meshing with the rack 23, so that one end of the pedal body 21 moves inside the retreat groove 1021 to the upper end of the elevator gap 1001, thereby achieving the automatic overlap above the elevator gap 1001 when the elevator door 121 is opened, eliminating the need for manual overlap of the pedal body 21, saving manpower, and improving overall construction efficiency.

[0082] Similarly, when closing the elevator door 121, it is only necessary to control the drive motor 114 to rotate in the opposite direction to drive the elevator door 121 to move downward until it is closed. At the same time, the drive motor 114 also synchronously drives the pedal body 21 to move completely into the retreat groove 1021. Since the working principle of this process is the same as the principle of the elevator door 121 opening process, it will not be repeated here.

[0083] like Figure 4-5 As shown, since the distance the elevator door 121 rises during each opening process is greater than the distance the pedal body 21 moves outward along the retreat groove 1021, the present invention sets the outer diameter of the fifth bevel gear 1182 to be smaller than the outer diameter of the sixth bevel gear 1191. This allows the rotational speed of the third driven shaft 119 relative to the second driven shaft 118 to be reduced during the transmission process between the fifth bevel gear 1182 and the sixth bevel gear 1191. This compensates for the fact that the distance the elevator door 121 rises is greater than the distance the pedal body 21 moves outward along the retreat groove 1021, ensuring that when the elevator door 121 rises to its highest point, the pedal body 21 can be exactly overlapped above the elevator gap 1001.

[0084] like Figure 5 , Figure 9 As shown, in addition, the present invention places the pedal body 21 inside the retreat groove 1021 so that each time the pedal body 21 is stored, the pedal body 21 can automatically move into the retreat groove 1021, ensuring that the pedal body 21 does not occupy the space inside the elevator body 102, thereby improving the space utilization rate of the elevator body 102.
