Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
Referring to fig. 1 and 2, an embodiment of the present utility model includes:
A spliced elevator upper sill structure, the spliced elevator upper sill structure comprising: the back plate 1 and the guide rail 2 are formed by one-step metal castings, and the guide rail 2 is fixed on the back plate 1 through a fastening bolt 3; the guide rail 2 comprises a guide rail seat 201, the front end of the guide rail seat 201 is a sliding plate mounting end, the rear end of the guide rail seat is a backboard splicing end, the sliding plate mounting end is provided with two hanging rails, the two hanging rails are an upper hanging rail 202 and a lower hanging rail 203, the upper hanging rail 202 and the lower hanging rail 203 are respectively arranged on a central line of a front end face 204 of the front end of the guide rail seat 201, the top end of each hanging rail is provided with an R-angle structure, the R-angle structure protrudes out of a plane where the front end face 204 is located, the guide rail seat 201 is further provided with a plurality of bolt holes 205 penetrating through the front end and the rear end along the central line, and the backboard 1 is provided with connecting holes matched with the bolt holes 205. The portion of the bolt hole 205 located on the front end surface 204 of the guide rail seat 201 is a counter bore, so that the height of the fastening bolt 3 protruding from the front end surface 204 during installation can be reduced, and the landing door is prevented from colliding with the surface of the skateboard during running. The bolt hole 205 is a long waist hole, and can be adjusted in the horizontal direction when being conveniently installed.
The rear end of the guide rail seat 201 is provided with a groove 206 along the center line of the end surface, and the width of the groove 207 is larger than the diameter of the bolt hole 205. The groove 207 is arranged in the way that the contact area between the splicing end of the backboard and the backboard 1 can be reduced, the pressure of the contact surface is increased after the connection of the fastening bolt 3, the relative movement between the guide rail 2 and the backboard 1 during the landing door movement can be reduced, and the integral vibration is reduced. Friction lines 207 are further arranged on the contact surfaces between the two sides of the groove 207 and the backboard 1, so that the stability of the contact surface in the vertical direction can be further improved, and noise during use can be reduced.
When the elevator landing door is opened in actual use, the roller wheel surface arranged on the sliding plate device at the top of the landing door is clamped on the upper hanging rail 202 and moves horizontally along the direction of the upper hanging rail 202, and at the moment, as the tops of the upper hanging rail 202 and the lower hanging rail 203 are both R-angle structures protruding from the end face of the front end, friction between the plate surface and the front end face can be effectively prevented from affecting landing door operation.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
